From: Gaurav Sharma <gaurav.sharma_7@nxp.com>

Add the Analog IP to i.MX8MM SoC. iMX8MM and i.MX8MP uses
the same Analog IP so the analog ip source will be shared.

The ARM PLL divider control register (arm-pll-fdiv-ctl0) has
a different reset value on i.MX8MM (0x000fa030) compared to
i.MX8MP (0x000fa031). So iMX8MM will be overriding this property
with its own reset-value.
