When the Haswell-specific monotonic timer is used on an ASRock H81M-HDS
with a Pentium G3258, the following exception is generated, causing the
system to hang.
CPU Index 0 - APIC 0 Unexpected Exception:13 @ 10:7f7a3736 - Halting
Code: 0 eflags: 00010006 cr2: 00000000

The exception occurs when trying to read `MSR_COUNTER_24_MHz`, located
at 0x637. This MSR only exists on Haswell-ULT CPUs.
So, allow boards to use the TSC monotonic timer instead. They can do
this by placing `select TSC_MONOTONIC_TIMER` in the mainboard Kconfig.

The function domain_read_resources() didn't have any code to actually
reserve any resources - it was just creating an empty resource entry.
I looked at fixing it to actually reserve the space, but the values in
the registers at the point when this runs aren't the final values that
we want to reserve anyway, they're temp values with a range much larger
than we want to reserve.
I next looked at moving the amd_initcpuio() function earlier so that we
could get the correct values for the registers, but even that doesn't
give us what we really want.
Ultimately removing this whole function seems to be the right thing.

Add the base ACPI support for the Wilco embedded controller, using
ASL 2.0 syntax throughout.
This includes the EC device and its resources, as well as the layout
for the EC RAM and the functions needed to read and write to the EC RAM.
The EC RAM address space is typically read/write, and so the ACPI EC
device expects that a defined Field can be read and/or written. With
this EC the read and write address spaces are different. For example,
a read from address zero will return data that is unrelated to what a
write to address zero expects.
This makes using a typical OperationRegion to describe the EC RAM
address space somewhat impracticle, since field definitions would
overlap. Instead, methods are provided for reading and writing to an
EC RAM offset, and the EC RAM layout is defined as a Package that
describes offset+mask for read or write fields within the EC RAM.
