The following structures are not modified in these drivers.
- struct meson_bank
- struct meson_pmx_bank
- struct meson_pmx_func
- struct meson_pmx_group
- struct meson_pinctrl_data
- struct meson_axg_pmx_data
Constifying these structures moves some data to a read-only section, so
increase overall security.

Compile tested-only.
In order to compile them, I've updated Kconfig to add some "| COMPILE_TEST"
on 'depends' line.
Should it be useful, I can send a patch to add it, but I don't think it
would be that useful.
Changes in v2:
- Merge 3 patches into only 1 [Jerome Brunet]
- Add constification of struct meson_pinctrl_data and
struct meson_axg_pmx_data [Jerome Brunet]
v1: https://lore.kernel.org/all/cover.1723022467.git.christophe.jaillet@xxxxxxxxxx/
