clk: imx: clk-composite-93: check white_list

Browse source

The CCM ROOT AUTHEN register WHITE_LIST indicate:
Each bit in this field represent for one domain. Bit16~Bit31 represent
for DOMAIN0~DOMAIN15 respectively. Only corresponding bit of the domains
is set to 1 can change the registers of this Clock Root.

i.MX93 DID is 3, so if BIT(3 + WHITE_LIST_SHIFT) is 0, the clk should be
set to read only. To make the imx93_clk_composite_flags be reusable,
add a new parameter named did(domain id);
