stm32mp25-pinctrl.dtsi gathers all pinctrl groups from current and future
STM32MP25-based boards. Some groups may remain unused by any board,
resulting in wasted binary space.
Adding /omit-if-no-ref/ to the groups will remove unused groups from the
device tree blobs.
Use the following regex to update the file:
's/^\t[^:]\+: [^ ]\+ {$/\t\/omit-if-no-ref\/\n&/'
Also, merge the duplicated pinctrl_z node.
