GPIO_USE_SEL[31:0] — R/W. Each bit in this register enables the corresponding
GPIO (if it exists) to be used as a GPIO, rather than for the native function.
0 = Signal used as native function.
1 = Signal used as a GPIO.

GP_IO_SEL[31:0] — R/W. When configured in native mode (GPIO_USE_SEL[n] is
0), writes to these bits have no effect. The value reported in this register is undefined
when programmed as native mode.
0 = Output. The corresponding GPIO signal is an output.
1 = Input. The corresponding GPIO signal is an input.
The following bits are always 1 because they are unmuxed: 6:10,12:15, 24:25
The following bits are not implemented because they are determined by the
Desktop Only /Mobile Only/Ultra Mobile configuration: 16, 18, 20, 32
If GPIO[n] does not exist, then the bit in this register will always read as 0 and
writes will have no effect.
After a full reset (RSMRST#) all multiplexed signals in the resume and core
wells are configured as their default function. After just a PLTRST#, the GPIO in
the core well are configured as their default function.
When configured to GPIO mode, the multiplexing logic will present the inactive
state to native logic that uses the pin as an input.
All GPIOs are reset to the default state by CF9h reset except GPIO24
