The existing helpers for reading/writing MSRs (rdmsr, wrmsr) require use
of the struct `msr_t`, which splits the MSR value into two 32 bit parts.
In many cases, where simple 32 bit or 64 bit values are written, this
bloats the code by unnecessarly having to use that struct.
Thus, introduce the helpers `msr_read` and `msr_write`, which take or
return `uint64_t` values, so the code condenses to a single line or two,
without having to deal with `msr_t`.
Example 1:
~~~
msr_t msr = {
.lo = read32((void *)(uintptr_t)0xfed30880),
.hi = 0,
};
msr.lo |= 1;
wrmsr(0x123, msr);
~~~
becomes
~~~
uint32_t foo = read32((void *)(uintptr_t)0xfed30880);
msr_write(0x123, foo | 1)
~~~
Example 2:
~~~
msr_t msr = rdmsr(0xff);
uint64_t msr_val = (msr.hi << 32) | msr.lo;
~~~
becomes
~~~
uint64_t msr_val = msr_read(0xff);
~~~

This adds full EINJ support with trigger action tables. The actual
error injection functionality is HW specific. Therefore, HW specific
code should call acpi_create_einj with an address where action table
resides. The default params of the action table are filled out by the
common code. Control is then returned back to the caller to modify or
override default parameters. If no changes are needed, caller can
simply add the acpi table. At runtime, FW is responsible for filling
out the action table with the proper entries. The action table memory
is shared between FW and OS. This memory should be marked as reserved
in E820 table.
Tested on Deltalake mainboard. Boot to OS, load the EINJ driver (
modprobe EINJ) and verify EINJ memory entries are in /proc/iomem.
Further tested by injecting errors via the APEI file nodes. More
information on error injection can be referenced in the latest ACPI
spec.

Some platforms which have large amounts of RAM and also write-combining
regions may decide to drop the WC regions in favor of the default when
preserving MTRRs for the OS. From a data safety perspective, this is
safe to do, but if, say, the graphics framebuffer is the region that is
changed from WC to UC/WB, then the performance of writing to the
framebuffer will decrease dramatically.
Modern OSes typically use Page Attribute Tables (PAT) to determine the
cacheability on a page level and usually do not touch the MTRRs. Thus,
it is believed to be safe to stop reserving MTRRs for the OS, in
general; PentiumII is the exception here in that OSes that still
support that may still require MTRRs to be available. In any case, if
the OS wants to reprogram all of the MTRRs, it is of course still free
to do so (after consulting the e820 table).
