[PATCH v2 00/32] pinctrl: mediatek: Enable module build support for all drivers

[Justin Yeh]

This series enables all MediaTek pinctrl drivers to be built as loadable
kernel modules. This is required for Android GKI (Generic Kernel Image) +
vendor_dlkm deployments where vendor-specific drivers must be kept separate
from the GKI vmlinux.

Each patch adds MODULE_LICENSE("GPL") and MODULE_DESCRIPTION() macros where
missing, and changes the Kconfig option from bool to tristate. This allows
these drivers to be properly packaged as vendor kernel modules while
maintaining the existing built-in option.

Changes in v2:
  * Squash MODULE_LICENSE and tristate changes into single patch per driver
  * Extend fix to all MediaTek pinctrl drivers (32 total), not just MT8189
  * Add Android GKI + vendor_dlkm context to cover letter
  * Add MODULE_DESCRIPTION() where it was missing
  * Add Fixes: tags referencing the original commits that added each driver
