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.

_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.
BRANCH=None
BUG=None
TEST=Built and booted Kevin without serial

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.
