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.

For version 2 extend the TMUV2_TMSAR() write loop over all site_ids
registered for a particular SoC and actually use the site_id rather
than always just the first [0] (which for the LX2080 would be a
problem given there is no site0).
Later, while version 2 adds the SITEs to enable to TMSR in bits 0..<n>,
version 1 (e.g., LS1028, LS1046, LS1088) add MSITEs to TMR
bits 16..31 or rather 15..0(16-<n>). Adjust the loops to only enable
the site_ids listed for the particular SoC for monitoring. This now
also deals with sparse site_ids (not starting at 0, or not being
contiguous).

Add a driver for NXP LS1088a clockgen support which passes
configuration information to QorIQ clockgen class.
The implementaiton started off as copy of ls1028 support and was
adjusted accordingly.

It adds the PIC functionality on top of qoriq_gpio driver.
We need a separate module since the powerpc PIC API is completely
different than on other architectures.
Two types of intr_map_data are supported:
INTR_MAP_DATA_GPIO and INTR_MAP_DATA_FDT.
This way interrupts can be allocated using the userspace gpio
interrupt allocation method, as well as directly from simplebus.
The latter can be used by devices that have its irq routed to a GPIO pin.

If anything goes wrong during attach() it is handled with a 'goto fail'
which calls sysctl_ctx_free(). But the sysctl context doesn't get
initialized until very late in attach(), so almost any error just results
in a segfault. Move the sysctl_ctx_init() call to the beginning of the
attach() function, so that it is done before any errors can happen that
will lead to freeing the context.
On some DesignWare PCIe controllers accessing config registers of slots
whose link is down triggers a SError. Because of that we need to check the
link status before any acceses config space.
Due to a typo link was always reported up.
This fixes a SError that occured during boot on LS1028A-RDB.

Summary:
They're nearly identical, so don't use two copies. Merge the newer
driver into the older one, and move it to a common location.
Add the Semihalf and associated copyrights in addition to mine, since
it's a non-trivial amount of code merged.

This patch adds a GPIO controller support targeted for NXP LS1046A
SoC. The driver implements the following features:
* setting direction of each pin (IN or OUT)
* setting the mode of output pins (PUSHPULL or OPENDRAIN)
* setting the state of each output pin (1 or 0)
* reading the state of each input pin (1 or 0)

This patch adds classes and functions that can be used with various NXP
QorIQ Layerscape SoCs.
As for the clock topology - there is single platform PLL, which supplies
clocks for the peripheral bus and additional PLLs for CPU cores. There
can be multiple core PLLs (For example - LS1046A has two PLLs - CGAPLL1
and CGAPLL2). Each PLL has fixed dividers on output. The core PLLs
are not accessible from dts.
This is a preparation patch for NXP LS1046A SoC support.
