arch: mach-k3: Fix incorrect mapping of higher DDR addresses as device memory
Entry for physical address 0x500000000 in memory map table for MMU
configuration is spilling over and inadvertently making DDR available at
higher address (above 4GB address space) get mapped as device memory
(nGnRnE).
Fix this by adjusting entry size. Tested on AM62A SK. Before this patch:
=> time crc32 0x881000000 0x20000000
crc32 for 881000000 ... 8a0ffffff ==> 7f34d7ca
time: 1 minutes, 14.716 seconds
After patch:
=> time crc32 0x881000000 0x20000000
crc32 for 881000000 ... 8a0ffffff ==> 7f34d7ca
time: 2.710 seconds
