The “mcu_pm_bclk_ck_cg” clock is used by co-processors and should not be

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

It's still a breakage. Besides, have you tried to add it as CLK_IS_CRITICAL? :-)

As I said to Conor, I can fix the driver index issue (patch 2/2) without fixing the binding (using CLK_IGNORE_UNUSED but CLK_IS_CRITICAL works too).
