Revert "elog: Use the RTC driver interface instead of reading CMOS directly."

This reverts commit 474313d1b6556ad8b3e6750a4096b5735cbfc846.

This reverted commit was applied out of sequence and there are a number
of dependencies that need to be in place prior to adding it. Remove it
for now.

nyan*: enable CLAMP_INPUTS

Enable pinmux clamp function to avoid pinmux conflict.
For pins which are configured to tristate enabled, the inputs to the
controller will be clamped to zero. This can be used to avoid pinmux
conflicts since the tristate bit is set to 1 in the power-on-reset
pinmux setting.
With pinmux clamp enabled, we need to configure all the input pins
to tristate disabled.

x86: Initialize SPI controller explicitly during PCH init

This ensures that SPI is ready when eventlog code is used.

x86 platforms which use eventlog invoke elog_clear() in GSMI and
elog_add_event_raw() when deciding the boot path based on ME status.
For the SMM case spi_init() is called during the finalize stage in
SMM setup. For the boot path case we can call spi_init() at the
beginning of BS_DEV_INIT and it will be ready to use when the boot
path is determined from the ME status.

In order to protect ourselves from the kernel driver not honoring or
placing the correct frequency in the backlight register always set one.
This code path picks 200Hz as the default if nothing is specified in

the eDP panel specs we've seen being used on baytrail devices.
