AM65SW-149 arm: mach-k3: arm64-mmu: increase NR_MMU_REGIONS

When configuring the MMU, the am654_mem_map array is traversed until
size and attrs fields are both zero. This leads to an out-of-bounds
memory access and potential MMU misconfiguration when am654_mem_map is
not large enough to contain the list terminator. To fix this, we
guarantee am654_mem_map is large enough by increasing NR_MMU_REGIONS
to account for cases where CONFIG_NR_DRAM_BANKS is less than two.
