kmsro: sync Android.mk GALLIUM_TARGET_DRIVERS
Sync Android.mk GALLIUM_TARGET_DRIVERS names from kmsro meson.build, notably adding the missing mediatek, meson and rockchip display drivers names.
It also fixes the imx name into imx-drm as referenced in meson.build and src/gallium/targets/dri/target.c
