Add support for decoding pressed keys as a bitmap. The keys in the
bitmap are described in the interface specific HID descriptor. Some
keyboards even have multiple input interfaces, only using the bitmap
method when the event array is full. That typically means when more
than seven keys are pressed simultaneously.
The internals of the USB keyboard driver have been slightly reworked
to keep track of all keys in a single bitmap having 256 bits. This
bitmap is then divided into blocks of 64-bits as an optimisation.
Simplify automatic key repeat logic, because only the last key pressed
can be repeated.

It was saved from the initial purge of drivers in fcp-101 due to being
the onboard Ethernet device on a number of sparc64 machines. Now that
sparc64 is gone, it serves little purpose (PCI cards exist, but are rare
and are unlikely to have been deployed outside Sun systems).

Platform (N1SDP).
Neoverse N1 is a high-performance ARM microarchitecture designed
by the ARM Holdings for the server market.
The PCI part on N1SDP was shipped untested and suffers from some
integration issues.
For instance accessing to not existing BDFs causes System Error
(SError) exception. To mitigate this, the firmware scans the bus,
catches SErrors and creates a table with valid BDFs. That allows
us to filter-out accesses to invalid BDFs in this driver.
Also the root complex config space (BDF == 0) has an unusual
location in memory map, so remapping accesses to it is required.
Finally, the config space is restricted to 32-bit accesses only.
This was tested on the ARM boxes kindly provided by the ARM Ltd
to the DARPA CHERI Project.

riscv cores.
GFE cores come with standard DTS file that lacks standard 'dmas ='
property, which means xae(4) could not find a DMA controller to use.
The 'dmas' property could not be added to the DTS file because the
ethernet controller and DMA engine parts in Linux are implemented
in a single driver.
Instead of 'dmas' property the standard Xilinx 'axistream-connected'
property is provided, so fallback to use it instead.

Currently the Xen console is always attached with priority CN_REMOTE
(highest), which means that when booting with a single console the Xen
console will take preference over the VGA for example, and that's not
intended unless the user has also selected to use a serial console.
Fix this by lowering the priority of the Xen console to NORMAL unless
the user has selected to use a serial console. This keeps the usual
FreeBSD behavior of outputting to the internal consoles (ie: VGA) when
booted as a Xen dom0.

In legacy VirtIO drivers, the header must be PCI endianness (little) and the
device-specific region is encoded in the native endian of the guest.
This patch makes the access (read/write) to VirtIO header using the little
endian order. Other read and write access are native endianness. This also
sets the device's IO region as big endian if on big endian machine.

Follow the TCG_PC_Client_Platform_TPM_Profile_PTP_2.0_r1.03_v22

tpmtis_go_ready() read the value of the TPM_STS register, ORed
TPM_STS_CMD_READY with it, and wrote it back. However, the TPM Profile
(PTP) specification states that only one bit in the write request value may
be set to 1, or else the entire write request is ignored.
Fix by just writing TPM_STS_CMD_READY.
Similarly, remove the call which clears the TPM_STS_CMD_READY flag in the
same function. It was being ignored for the same reason.
