a092f33305 imx: imx8ulp: add ND/LD clock
Add a new ddr script, defconfig for ND
Configure the clock for ND mode
changing A35 to 960MHz for OD mode
Update NIC CLK for the various modes
Introduce clock_init_early/late, late is used after pmic voltage
setting, early is used in the very early stage for upower mu, lpuart and
etc.

Note: NIC runs at 324MHz, 442MHz has some random kernel hang issue with
cpuidle enabled now.

Add basic i.MX8ULP support

For the MMU part, Using a simple way the calculate the MMU size to avoid
default heavy calcaulation. And align address and size in the table
settings to 2MB or 4GB as much as possible. So we can reduce the 4K page
allocations in MMU table which will spends much time in create the
page table
