This patch removes checks that ensure EC to be in RO for recovery
boot. We do not need these checks because when recovery is requested
automatically (as opposed to manually), we show 'broken' screen where
users can only reboot the device or request recovery manually.
If recovery is requested, Depthcharge will check whether EC is in RO
or not and recovery switch was pressed or not. If it's a legitimate
manual recovery, EC should be in RO. Thus, we can trust the recovery
button state it reports.
This patch removes all calls to google_chromeec_check_ec_image,
which is called to avoid duplicate memory training when recovery
is requested but EC is in RW.

This patch implements a relatively simple hash-based verification scheme
for downloaded files (tarballs):
After buildgcc downloads a file or notices that it has already been
downloaded, it hashes the file, and compares the hash against the known
hash stored in util/crossgcc/sum/$filename.cksum. Two errors can occur:
1. The hash file is missing. In this case, crossgcc asks the user to
verify the authenticity of the downloaded file. It also calculates
its hash and stores it in util/crossgcc/sum/$filename.cksum.calc.
If the file is authentic, the user may rename the calculated hash
file to $filename.cksum, so that it can be found the next time
buildgcc is started.
2. The known hash and the calculated hash differ. This is the case that
this patch seeks to protect against, because it may imply that the
downloaded file was unexpectedly changed, either in transit
(Man-in-the-Middle attack) or on the file server that it was
downloaded from. If buildgcc detects such a hash mismatch, it asks
the user to delete the downloaded file and retry, because it can also
be caused by a benign network error. If, however, the error persists,
buildgcc can't continue without risking that the user runs malicious
code, and it stops.
Note: The hash algorithm may be changed in the future, but for now I
left it at SHA-1, to avoid bloating this patch.

Currently the WCOMCOHO registers a reset delay of 110ms to execute their
_ON_ asl power on method. This seems to be correct as per WACOM product
design specifications but it introduces an unwanted delay in overall system
resume time. This delay should be removed from ACPI critical path since the
entire kernel resume gets blocked on this sleep call unless this is over. In
the kernel I2C communication with WACOM driver starts with the resume
callbacks of I2C HID driver which gets triggered after display is completely
resumed. The display resume process takes at least 230ms so it's safe to
reduce the delay from coreboot and unblock the critical ACPI path.

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.

Rewrite the handler to be more compact and extendable. The old
functionality is duplicated after the rewrite. All SMI source registers
(except for SmiSciStatus) behave identically so these are consolidated.
Register 0x80 contains sources 0-31, 0x81 sources 32-63, and so on.
Create a table of mini-handlers to be supported in the soc directory.
As SMI sources are discovered, attempt to find the corresponding handler
and then execute it.

RK3399 has a pin that can decide whether GPIO port 1 is driven with 1.8V
or 3.0V. We thought this mechanism was disabled by default, but it turns
out it wasn't. We want to use that pin as an output GPIO on Scarlet so
we need to reconfigure the respective SoC controls before we do that. It
seems that we also need to explicitly pinmux the pin away from that
special function (to normal GPIO) or weird things happen on some boards.
