Currently, compression is only allowed at subheader level (e.g. cbfs_stage,
cbfs_payload_segment). This change adds compression field to each file's
header so that any cbfs file can be compressed.
With the necessary additions in coreboot and libpayload, the following sample
code can load a compressed file:
const char *name = "foo.bmp";
struct cbfs_file *file = cbfs_get_file(media, name);
void *dst = malloc(ntohl(file->uncompressed_size));
dst = cbfs_get_file_content(media, name, type, file, dst);
cbfs_stage and cbfs_payload_segment continue to support compression at
subheader level because stages and payloads have to be decompressed to the load
address, which is stored in the subheader. For these, file level compression
should be turned off.

In the gm45 code, IOMMU is always selected to be enabled. Instead
this patch removes the Kconfig symbol and its dependencies. This leads
to the same effect without the need for the symbol.
The symbol is still used in the K8 code as it's not selected, simply
defaulted to being enabled, and one of the mainboards disables it.

Add the timestamp tick frequency within the timestamp table so
the cbmem utility doesn't try to figure it out on its own. Those
paths still exist for x86 systems which don't provide tsc_freq_mhz().
All other non-x86 systems use the monotonic timer which has a 1us
granularity or 1MHz.
One of the main reasons is that Linux is reporting
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq as the true
turbo frequency on turbo enables machines. This change also fixes
the p-state values honored in cpufreq for turbo machines in that
turbo p-pstates were reported as 100MHz greater than nominal.

The BUNIT controls the policy for read/write access to physical
memory. For the SMRAM range the policy was not allowing dirty
evictions to the SMRAM when the core causing the eviction was not
in SMM mode. This could happen when the SMM handler dirtied a line
and then RSM'd back into non-SMM mode. The cache line was dirtied
while in SMM mode, but when that particular cache line was evicted
it would be silently dropped. Fix this by allowing the BUNIT to honor
writes to the SMRAM range while the evicting core is not in SMM mode.
The core SMRR msr provides the mechanism for disallowing general access
to the SMRAM region while it is not in SMM mode.
