The Stoney Ridge APU has only two internal UARTs. Add checks for
invalid settings. When enabling the UART, return if the console is
on any UART not equal 0 or 1. The base address returned is 0 if an
invalid configuration is used. All callers check the return value
before using the returned value. Finally, provide an assert at the
earliest availability of the console to get the notice into the
cbmem console.

The Stoney Ridge UART and AMBA devices must be powered and report power
and clock OK prior to using the coreboot serial console. The code used
to have a delay to wait for the power and clock, but didn't check the
OK bits. This caused long delays on a reboot, as each byte would time out
until the console was reset again at romstage.
This change also removes the UART reset. The device has just been
powered and is in reset already. Testing indicates the reset isn't
needed.
BUG=b:65853981
TEST=Boot to Chrome OS, run the reboot command, verify that the long
delay is gone.

Add dedicated CAR setup and teardown functions and Kconfig
options to force their inclusion into the build. The .S files
are mostly duplicated code from the old cache_as_ram.inc file.
The .S files use global proc names in anticipation for use with
the Kconfig symbols C_ENVIRONMENT_BOOTBLOCK and POSTCAR_STAGE.
Move the mainboard romstage functionality into the soc directory
and change the function name to be compatible with the call
from assembly_entry.S. Drop the BIST check like other devices.
Move InitReset and InitEarly to bootblock. These AGESA entry
points set some default settings, and release/recapture the
AP cores. There are currently some early dependencies on
InitReset. Future work should include:
* Pull the necessary functionality from InitReset into bootblock
* Move InitReset and InitEarly to car_stage_entry() and out of
bootblock
- Add a mechanism for the BSP to give the APs an address
to call and skip most of bootblock and verstage (when
available) (1)
- Reunify BiosCallOuts.c and OemCustomize.c
(1) During the InitReset call, the BSP enables the APs by setting
core enable bits in F18F0x1DC and APs begin fetching/executing
from the reset vector. The BSP waits for all APs to also
reach InitReset, where they enter an endless loop. The BSP
sends a command to them to execute a HLT instruction and the
BSP eventually returns from InitReset. The goal would be to
preserve this process but prevent APs from rerunning early
code.

Correct the majority of reported errors and mark most of the
remaining ones as todo. (Some of the lines requiring a >80
break are indented too much currently.) Some of the alignment
in hudson.h still causes checkpatch errors, but this is
intentionally left as-is.
Also make other misc. changes, e.g. consistency in lower-case
for hex values, using defined values, etc.
These changes were confirmed to cause no changes in a Gardenia
build. No other improvements were made, e.g. changing to helper
functions, or converting functions like __outbyte().
