This patch removes the "freeze" state from the supported power state list. This patch is mandatory on STM32MP15 platform as we can't support "freeze" power state due to hardware watchdog. Indeed, on STM32MP15 SOC it's not possible to stop and reload hardware watchdog through registers access. So during the freeze sequence the hardware watchdog is no longer reloaded and then platform reboots.
