MLK-25462: imx8mp_evk: Add nominal drive mode support for LPDDR4 EVK
Add dedicated defconfig for iMX8MP nominal drive mode with VDD_SOC
at 0.85V, LPDDR4 at 3200MTS (1600Mhz clock).
Set GIC clock to OD frequency (500Mhz) only when OD mode is used,
i.e. VDD_SOC = 0.95V. For LPDDR4 EVK in ND and DDR4 EVK, use default
400Mhz for ND VDD_SOC.
Set HSIO AXI clock to 400Mhz for ND mode
