Subject: [PATCH v2 1/2] dt-bindings: clock: mediatek: replace unusable
 clock

The “mcu_pm_bclk_ck_cg” clock is used by co-processors and should not be
added to the kernel driver, otherwise the CPU just halt and the board is
rebooted by the wathdog.

Instead, add the "aes_top0_bclk_ck_cg" missing clock to prevent
re-shuffling index and then preserve the ABI.
