6.12-stable review patch. If anyone has any objections, please let me know.

commit 83964a29379cb08929a39172780a4c2992bc7c93 upstream.
The current solution for powering off the Apalis iMX6 is not functioning as intended. To resolve this, it is necessary to power off the vgen2_reg, which will also set the POWER_ENABLE_MOCI signal to a low state. This ensures the carrier board is properly informed to initiate its power-off sequence.
The new solution uses the regulator-poweroff driver, which will power off the regulator during a system shutdown.
