clk: imx: composite-8m: Enable gate clk with mcore_booted

Browse source

[ Upstream commit 8f32e9dd09 ]

Bootloader might disable some CCM ROOT Slices. So if mcore_booted set with
display CCM ROOT disabled by Bootloader, kernel display BLK CTRL driver
imx8m_blk_ctrl_driver_init may hang the system because the BUS clk is
disabled.

Add back gate ops, but with disable doing nothing, then the CCM ROOT
will be enabled when used.
