Coming Kevin revisions will switch back to an I2C TPM. This patch adds
the required configuration options and code to support that. Since the
TPM type can currently only be changed at compile time, we can no longer
support older Kevins with the same image. In order to build for Kevin
revisions < 5, you have to explicitly override the CONFIG_GRU_HAS_TPM2.

We need to enable DRAM ODT on kevin/gru board to improve the
DRAM signal. Note, if the DRAM ODT is enabled and set to 120ohms,
the sdram VREF need to adjust to 840mv.
This patch also makes following changes:
1. For compatiblity with the old board, add the
"sdram-lpddr3-hynix-4GB-666-no-odt.inc" and
"sdram-lpddr3-hynix-4GB-800-no-odt.inc" files
which do not enable sdram ODT.
2. Delete the 300MHz dram inc file. The 300MHz sdram config just
reduced 666MHz to 300MHz based on the 666MHz config file, and it is
not stable, so delete it.
3. Delete the 928MHz dram inc file, 928MHz sdram config still in
debuging, delete it for now.

_Static_assert() gets evaluated even when the code path it's in is
unreachable (e.g. inside an if (0) block). Unfortunately, Kconfigs that
depend on a disabled Kconfig are always 0, meaning that
CONFIG_CONSOLE_SERIAL_UART_ADDRESS on Gru cannot evaluate to UART2 when
CONFIG_CONSOLE_SERIAL (which it depends on) is disabled. Switch the
condition it is wrapped in to a preprocessor #if so that the
_Static_assert() is not evaluated when building without serial support.

We want to be able to easily change SDRAM clock rate for debugging

Same configs are used for all rk3399 boards at 200, 666 and 800 MHz.
Kevin board does not run reliably at 666 MHz, an option for it is
added to run at 300 MHz, this option is available to Kevin only.
There is not much room left in the coreboot romstage section, this is
why the config file for 928 MHz is being added with this patch but is
not included in the code, one of the lower frequency options will have

The idea is that they stay low unless we know that we booted from SPI
flash. As this code runs in SPI flash - it is ok to turn these rails
on as soon as possible, and pp3000 rail it is essential for UART to
work.
Kevin rev1 and Gru designs are going to be using these pins to
control these rails. Kevin rev1 had those GPIO pins routed to two
chip enable signals, it is save to assert them high.

The Board ID on the Gru family of boards is determined by reading the
voltage from a resistor divider, each hardware revision is supposed to
have a unique resistor ratio, which allows to distinctly tell between
different Board ID.
While the long time approach to mapping resistor ratios (and voltages)
into Board ID remains under discussion, we know for sure the values
for Proto 1 and Proto 2. Let's just use them for now.
Since Board ID can be queried multiple times during boot, ideally it
should be read once and placed in the coreboot table to be available
to all coreboot stages. For now we just cache it so that at least
during the same stage the ADC has to run only once.
BRANCH=None
