The pin 327 was supposed to be used as a voltage control line for the
SD card regulator, but the SD card port1 does not support UHS-I.  It
only supports 3.3V signaling, hence this pin is pointless.

Just a note about the background.  At first, hardware engineers tried
to implement the UHS for this port.  Then, they needed to shrink the
silicon die size, and gave up the UHS, but forgot to remove the pin
assignment.

Add the pinctrl driver for Meson-G12A SoC which share the similar IP as
the previous Meson-AXG SoC, both use same pinmux ops (register layout).
A new driver is needed here due to the differences in the pins.

Starting from Meson-AXG SoC, the pinctrl controller block use 4
continues register bits to specific the pin mux function, while comparing
to old generation SoC which using variable length register bits for
the pin mux definition. The new design greatly simplify the software model.

For the detail example, one 32bit register can be divided into 8 parts,
each has 4 bits whose value start from 0 - 7, each can describe one pin,
the value 0 is always devoted to GPIO function, while 1 - 7 devoted to
the mux pin function.

Please note, the GPIOE is actually located at AO (always on) bank.

When requesting a gpio as an interrupt, we should make sure to mux the
pin as the GPIO function and configure it to be an input so that various
functions or output signals don't affect the interrupt state of the pin.
So far, we've relied on pinmux configurations in DT to handle this, but
let's explicitly configure this in the code so that DT implementers
don't have to get this part right.

function when the gpio is use from gpiolib.
