[PATCH] mach-k3: j722s: unlock mmr after spl_early_init

[Udit Kumar]

unlocking control mmr before spl_early_init leads to
unpredicable behaviour.
So unlock it after spl_early_init.

Fixes: 5e291ee34fd4 ("arch: mach-k3: Introduce basic files to support J722S SoC family")

On HS-SE of J722S in particular, enable_mcu_esm_reset function is not able to reset bit-17 of ctrl mmr CTRLMMR_MCU_RST_CTRL.
Which leads to wdt is not functional. With this change
bit-17 was getting reset properly on HS-SE and HS-FS devices.
