involving the binary first numbering scheme.
- Rialto's SDRAM mapping is different, so I padded its SDRAM entries

According to USB 2.0 Spec Table 7-7, the High-speed squelch
detection threshold Min 100mV and Max 150mV, and we set USB
2.0 PHY0 and PHY1 squelch detection threshold to 150mV by
default, so if the amplitude of differential voltage envelope
is < 150 mV, the USB 2.0 PHYs envelope detector will indicate
it as squelch.
On Kevin board, if we connect usb device with Samsung U2 cable,
we can see that the impedance of U2 cable is too big according
to the eye-diagram test report, and this cause serious signal
attenuation at the end of receiver, the amplitude of differential
voltage falls below 150mV.
This patch aims to reduce the PHY0 and PHY1 otg-ports squelch

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

Some variants need the internal pull resistor on GPIO_SSUS_40
set explicitly to pull down rather than disabling the pull,
in order for the ram-id to be read correctly via GPIO.
Correct this by adding a function to enable and set the internal pull
and define its use as needed in the board's variant.h.
