This patch reworks PINCTRL_MSM to be a visible option, and
instead of having the various SoC specific drivers select
PINCTRL_MSM, this switches those configs to depend on
PINCTRL_MSM.
This is useful, as it will be needed in order to cleanly support
having the qcom-scm driver, which pinctrl-msm calls into,
configured as a module. Without this change, we would eventually
have to add dependency lines to every config that selects
PINCTRL_MSM, and that would becomes a maintenance headache.
We also add PINCTRL_MSM to the arm64 defconfig to avoid
surprises as otherwise PINCTRL_MSM/IPQ* options previously
enabled, will be off.

Add the "lcd-8bit" group to the "lcd" function.
As "lcd-24bit" is a superset of "lcd-8bit", in theory the former could
be modified to only contain the pins not already included in "lcd-8bit",
just like how it's done for the JZ4740 and JZ4725B platforms. However,
we can't do that without breaking Device Tree ABI, so in that case we
have no choice but to have two groups containing the same pins.

Abuse the pin function pointer to store the pin function value directly,
when all the pins of a group have the same function value. Now when the
pointer value is <= 3 (unsigned), the pointer value is used as the pin
function; otherwise it is used as a regular pointer.
This drastically reduces the number of pin function tables needed, and
drops .data usage by about 2 KiB. Additionally, the few pin function
tables that are still around now contain u8 instead of int, since the
largest number that will be stored is 3.
