The VDDIO to GEN2 I2C SCL/SDA pins is 1.8V and the external
pull-up voltage is 3.3V (the external 3.3V > I/O 1.8V) thus
the pinmux E_OD bit of these two pins needs to be set to
ensure GEN2 I2C pads work fine on 3.3V.
BRANCH=nyan
BUG=none
TEST=observed voltage drop from 3.3V to 2.36V on gen2 i2c
on blaze w/o this change. the waveform looks good on both
scl/sda pins w/ this change.

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.

The SPI drivers for tegra and exynos5420 have code in them which waits for a
frame header and leaves filler data out. The SPI driver shouldn't have support
for frame headers directly. If a device uses them, it should support them
itself. That makes the SPI drivers simpler and easier to write.
When moving the frame handling logic into the EC support code, EC communication
continued to work on tegra but no longer worked on exynos5420. That suggested
the SPI driver on the 5420 wasn't working correctly, so I replaced that with
the implementation in depthcharge. Unfortunately that implementation doesn't
support waiting for a frame header for the EC, so these changes are combined
into one.
BUG=None
TEST=Built and booted on pit. Built and booted on nyan. In both cases,
verified that there were no error messages from the SPI drivers or the EC
code.

These had been set to something fairly random which results in a very slow
clock on the bus itself. The new settings take into consideration the speed
the devices on the bus can run at. The TPM can't seem to handle speeds above
40KHz, but some documentation suggests that it should be able to handle up to
at least 100KHz.

The nyan_big mainboard is very similar to nyan, but will be different in a few
ways. For instance, the BCT will be different, and the GPIOs may need to be
configured slightly differently.
This change also adds prefixes to the kconfig variables in "choice" blocks
for both boards since having multiple instances of choice blocks with the same
options confuses kconfig even if all of the instances have mutually exclusive
dependencies.
