Peng Fan 0836c8604a clk: imx: add i.MX93 clk gate
i.MX93 LPCG is different from i.MX8M CCGR. Although imx_clk_hw_gate4_flags
is used here, it not strictly match i.MX93. i.MX93 has such design:
 - LPCG_DIRECT use BIT0 as on/off gate when LPCG_AUTHEN CPU_LPM is 0
 - LPCG_LPM_CUR use BIT[2:0] as on/off gate when LPCG_AUTHEN CPU_LPM is 1

The current implementation suppose CPU_LPM is 0, and use LPCG_DIRECT
BIT[1:0] as on/off gate. Although BIT1 is touched, actually BIT1 is
reserved.

And imx_clk_hw_gate4_flags use mask 0x3 to determine whether the clk
is enabled or not, but i.MX93 LPCG only use BIT0 to control when CPU_LPM
is 0. So clk disabled unused during kernel boot not able to gate off
the unused clocks.

To match i.MX93 LPCG, introduce imx93_clk_gate.
