Now that cpu_info() is no longer used by COOP_MULTITASKING, we no
longer need to set up cpu_info in SMM. When using CPU_INFO_V2, if
something does manage to call cpu_info() while executing in SMM mode,
the %gs segment is disabled, so it will generate an exception.

set regardless of the timer being enabled or disabled.
To be specification-compliant, only set that flag, when the hardware PM
Timer is enabled. This changes behaviour of all mainboards defaulting to
USE_PM_ACPI_TIMER=n.
Note: On platforms supporting uCode PM ACPI Timer emulation, this is
required, too, because emulation does not support `TMR_STS`. Any

Looks like nothing references this example. Remove it. If one needs an
example, there's several mainboards which contain an I/O trap handler.

This change splits CSE metadata structure (added to CBFS) into two
separate CBFS files (me_rw.hash and me_rw.version). Since `struct
cse_rw_metadata` is now used, it is dropped completely.
This change is being made in order to prepare for the upcoming changes
to stitch CSE binary at build time. Since the binary might not be
available pre-built, it complicates the order of operations for the
addition of CSE metadata structure and declaring hash and version as
CPPFLAGS_common. Instead rules can be enabled for individual CBFS file
targets for hash and version that ensure proper ordering as well.

TEST=Ensured that update works correctly on brya by forcing version
mismatch. In case of version match, no update is triggered.

The SHRM region needs to be 4 byte aligned, which make enabling
compression slightly more complicated. We need to map it to cached
memory before loading it and flushing to memory (in aligned chunks)
then remapping the address space back to device memory before
beginning execution of the SHRM region.
Also, did some cleanup in this file based on comments in CB:49392.
