MLK-15056 arm: imx: use static mapping for imx7ulp AIPSx memory space

The AIPSx address space of i.MX7ULP need to be mapped as SZ_1M block
in iRAM tlb for suspend code use. If we use ioremap to map these
address region into kernel space, we can't make sure that the returned
virtual address is 1M alignment. So we can map this address regions
as static, then if we use the ioremap to map these memory regions, it will
always return the virtual address of static mapping. So we can make sure
the virtual address is 1M aligned.
