For some mysterious reason GPIO_S0_NC22 is making the eDP panel
go entirely white when it is configured with internal pullup.
Since these (supposedly XDP related) pins are unknown functionality
lets set them to GPIO_DEFAULT instead of GPIO_NC.
Additionally the VBIOS is being changed to issue int15 callback
to determine the boot graphics device. If we list both LFP and EFP

The TPM driver expects to call i2c_read with zero address length. The i2c
driver wasn't prepared to handle that particularly in the case of reads
because it expected to send an address before switching over to read mode for

be read32 and write32 instead of readl and writel.

The goal is to make it so that we can actually use the #defines
without the code becoming a hideous, line-broken mess. As they were,
the #defines made code so ugly that it actually became less readable.
Additionally, a couple trivial issues were found and fixed:
- Removes duplicate AHB bus width #defines
- Removes a non-sensical #define that seems to be a result of an
incompleted copy+paste job.

This is essentially a direct port of CL:174505. It sets the EHCI
controllers Tx FIFO threshold setting to the recommended value for HOST
mode, which seems to help prevent FIFO underruns between the memory/AHB
and the host controller. This is necessary to get larger OUT transfers
to work, but there are still a few more general clock changes
concerning other AHB problems needed before they will really be usable.

Right now, firmware changes are rejected if the HWTest or VMTest
stages fail. This is unnecessary as firmware changes are very unlikely
to break these stages.
