i.MX8MP has similar architecture as i.MX8MN, but it has different
clk root and index, so add that to make i.MX8MP could use
the non-dm clock driver.

i.MX8MN has similar architecture with i.MX8MM, so it could reuse
the clock code of i.MX8MM, but i.MX8MN has different CCM root
configurations, so need a separate root entry.

Introduce clk implementation for i.MX8MM, including pll configuration,
ccm configuration. Mostly will be done clk dm driver,
but such as DRAM part, we still use non clk dm driver, because we
have limited sram.
