There was no 'early' call into the SoC code prior to console
getting initialized. Not having this enforces the mainboard to
drive the setup of the console which typically just ends up
calling into the SoC code. Provide a SoC early init call
to handle this without having to duplicate the same code
in mainboards utilizing the same SoC.

This patch ports the LZ4 decompression code that debuted in libpayload
last year to coreboot for use in CBFS stages (upgrading the base
algorithm to LZ4's dev branch to access the new in-place decompression
checks). This is especially useful for pre-RAM stages in constrained
SRAM-based systems, which previously could not be compressed due to
the size requirements of the LZMA scratchpad and bounce buffer. The
LZ4 algorithm offers a very lean decompressor function and in-place
decompression support to achieve roughly the same boot speed gains
(trading compression ratio for decompression time) with nearly no
memory overhead.
For now we only activate it for the stages that had previously not been
compressed at all on non-XIP (read: non-x86) boards. In the future we
may also consider replacing LZMA completely for certain boards, since
which algorithm wins out on boot speed depends on board-specific
parameters (architecture, processor speed, SPI transfer rate, etc.).

Stages are inconsistent with other memlayout regions in that they don't

_eprogram marks the actual end of the executable's memory footprint, not
the end of the area allocated in memlayout. Both of these are sometimes
useful to know, so let's add another set of symbols that allow the stage
areas to be treated more similarly to other regions.

When CONFIG_LP_TIMER_RDTSC is enabled honor the TSC information
exported in the coreboot tables as the cpu_khz frequency. That
allows get_cpu_speed() not to be called which currently relies
on the 8254 PIT. As certain x86 platforms allow that device
to be optional or turned off for power saving reasons, allow
a path where get_cpu_speed() is no longer called. Additionally,
this approach also allows the libpayload to not duplicate logic
that already exists in coreboot.
BUG=chrome-os-partner:50214
BRANCH=glados
TEST=Confirmed in payload TSC frequency is honored instead of
using get_cpu_speed().

The 8254 (Programmable Interrupt Timer) is becoming optional
on x86 platforms -- either from saving power or not including it
at all. To allow a payload to still use a TSC without doing
calibration provide the TSC frequency information in the coreboot
tables. That data is provided by code/logic already employed
by platform. If tsc_freq_mhz() returns 0 or
CONFIG_TSC_CONSTANT_RATE is not selected the coreboot table
record isn't created.
BUG=chrome-os-partner:50214
BRANCH=glados
TEST=With all subsequent patches confirmed TSC is picked up in
libpayload.
