On the TI CC32xx, the GPIO peripheral supports only 8 pins per port.
We should add assertions where appropriate to verify this.

Update driver code and board files to use new GPIO configuration flags
such as GPIO_ACTIVE_LOW. Also add implementation of new port_* driver
API as well as gpio_pin_interrupt_configure function.
The interrupt triggering on both edges is a remnant from the old
Quark SE which has a customized DesignWare GPIO block. So remove
the support for both edges as the board is no longer supported.

Change when we clear interrupt status to happen before we handle the
callbacks. As the callbacks might manipluate the GPIO state and cause
a GPIO interrupt. If we clear interrupt status after than we might
miss an interrupt.
Also only clear interrupts for interrupts that are we have enabled and
that were reported when we read from the interrupt status.

Gain values are specified with enumeration values that can't be used
to reverse the effects of scaling the input signal. Provide a
function that reverses the effect of the gain by scaling a measured
value.
Also provide a function that converts a raw measurement captured with
a reference voltage and specific gain and resolution to the
corresponding voltage in millivolts.

Introduces a new ft5336 touch panel driver for the keyboard scan (kscan)
interface. The driver currently uses a timer to periodically poll touch
data in the system work queue, but later it can be enhanced to use a
gpio interrupt instead of a timer.

ARM cores may have a per-core architected timer, which provides per-cpu
timers, attached to a GIC to deliver its per-processor interrupts via
PPIs. This is the most common case supported by QEMU in the virt
platform.
This patch introduces support for this timer abstracting the way the
timer registers are actually accessed. This is needed because different
architectures (for example ARMv7-R vs ARMv8-A) use different registers
and even the same architecture (ARMv8-A) can actually use different
timers (ELx physical timers vs ELx virtual timers).
So we introduce the common driver here but the actual SoC / architecture
/ board must provide the three helpers (arm_arch_timer_set_compare(),
arm_arch_timer_toggle(), arm_arch_timer_count()) using an header file
imported through the arch/cpu.h header file.
