Handle data-lanes property for pcie phy and set it accordingly.
This makes devices attached to pcie3 work properly.
For some RK3568 based boards, RTL8125B based device is
connected it. So with this, realtek-re-kmod driver attaches
and works.
Partially obtained from OpenBSD.
Tested on NanoPI-R5S, FireFly Station P2 boards.
On arm64 PCI config memory is expected to be mapped with a non-posted
device type. To handle this use the new bus_map_resource support in
arm64 to map memory with the new VM_MEMATTR_DEVICE_NP attribute. This
memory has already been allocated and activated, it just needs to be
mapped.

The order of asserting/deasserting the resets doesn't matter so use
the new hwreset_array to manage them all.

This can be eventually improved or simplified or fixed if necessary.
Following devices work with proper drivers and with the necessary clocks:
Native networking via eqos driver
USB3 and USB2
PCIe support is working but a bit picky about what hardware it supports (but so is Linux)
SD & (e)MMC
With the EDK2 loader video also works
Supported hardwares are Quartz64, NanoPI R5S and Firefly Station P2, more to come as DTS files gets done.
The RK3328 dts doesn't have the glue node so we need the dwc3 driver
to attach directly.

The pull-up/pull-down register offset was wrong on the Rockchip rk356x.
It was set such that the driver would modify the IOMUX control registers.
This seems to work with the current device tree files, but fails with
upstream files. Fix the offset so the later calculation has the correct
offset for the pull-up/pull-down control register.

It supports gpio type checking. Depending on gpio type some
register addresses are different.

With clang 15, the following -Werror warning is produced:
sys/arm64/rockchip/rk_spi.c:229:6: error: variable 'cnt' set but not used [-Werror,-Wunused-but-set-variable]
int cnt = 0;
^
The 'cnt' variable was in rk_spi.c when it was first added, but it
appears to have been a debugging aid that has never been used, so remove
it.

Changing mode on a pin (input/output/pullup/pulldown) is a bit slow.
Improve this by caching what we can.
We need to check if the pin is in gpio mode, do that the first time
that we have a request for this pin and cache the result. We can't do
that at attach as we are a child of rk_pinctrl and it didn't finished
its attach then.
Cache also the flags specific to the pinctrl (pullup or pulldown) if the
pin is in input mode.
Cache the registers that deals with input/output mode and output value. Also
remove some register reads when we change the direction of a pin or when we
change the output value since the bit changed in the registers only affect output
pins.
Node names for gpio bank were made generic in Linux 5.16 so stop
using them to map the gpio controller to the pin controller bank unit.

We should clean up on failure as it may panic the kernel later, e.g.
if we crate the rman, but fail to destroy it on attach faulure.

This is needed with some dtb files.
While here use a switch statement as the two options are mutually

- maximum number of bytes that can be sent is 32, not 8;
- previous interface required callers to bump sc->msg->len in addition
to setting sc->tx_slave_addr;
- because of the above there was an issue with writing one too many bytes
because sc->cnt is not advanced when the slave address is written;
- the inetraction between outer and inner loops was confusing as the former
was bounded on the number of bytes to write and the counter was
incremented by one, but the inner loop advanced four bytes at a time;
- the return value was incorrect in the tx_slave_addr case; one call place
had to use its own (and incorrect in some cases) notion of the write
lenth.
All of the above issues should be fixed.
Some sanity asserts are added.
All callers use the return value to program RK_I2C_MTXCNT.
iic_msg::len no longer needs to be hacked.
A constant is added to reflect the maximum number of octets that can be
sent or received in one go (they are the same).

No need to mask a uint8_t with 0xff, the mask covers the whole type.
Explcitly cast to uint32_t before bit shifting instead of relying on

Previously the driver would happily talk to addresses with no device

Previously the code would decalre the transfer complete after sending
first 31 bytes (plus the slave address) of a larger I2C write transfer.
That was tested using a large write to an EEPROM with 32-byte write page
size and a 2-byte address type. Such a transaction needed to send 34
bytes, 2 bytes for an offset and 32 bytes of actual data.
