Currently UART0 GPIOs are being put into native mode during FSP-S
stage, so have ramstage re-configure them back to regular GPIO mode.
GPP_C8 does not seem to be functioning properly when routed to the
APIC, possibly due to the UART0 being enabled even though it is unused,
which is required because UART0 is PCI 1e.0 and so must be present for
other 1e.x functions to be enumerated. Instead, use this pin as a GPIO
interrupt so it will be routed through the GPIO controller at IRQ 14.
GPP_C9 was inverted and was only working because the pin was being
re-configured in FSP-S.
Also export the reset gpio as a device property so it can be used by
the kernel driver, which will stop it from complaining at boot.
BUG=chrome-os-partner:61233
TEST=verify that the interrupt and device is functional in the OS

GPIO GPP_D22 controls the I2S buffer for isolating the I2S signals
when doing GPIO-driven I2S. This needs to be high by default so
the DSP can drive these signals, instead of low where it is enabled
for GPIO-driven I2S and the DSP cannot drive these signals.

Enable an internal pull-up on the power button input as a quick

BUG=chrome-os-partner:61312
TEST=tested on eve P0b to ensure quick power button press does

GPP_D12 needs an internal pull-up to get this rail working on
current boards. GPP_D0-GPP_D3 were changed from SPI interface
and I just missed this change earlier.

Put the UART pins into native mode in bootblock so they are not
floating when we try to communicate with H1 over I2C. Without
a serial console enabled BIOS these pins were not configured
until ramstage.

On this board i2c3 bus is connected to the display TCON, but it is
acting as the master when it has power so it can read from its own
EEPROM on the bus. In order to prevent any possible issues in S0
make these pins input on the SOC.
BUG=chrome-os-partner:58666
TEST=tested on eve board, but this bus was not used before so
there is no visible change in behavior.
