Peng Fan 9ef89ea9b0 arm: imx: basic i.MX8ULP support
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
