Arm platforms: Fix DRAM address macros

On AArch32, ARM_DRAM1_BASE and ARM_DRAM1_SIZE constants are currently
32-bit values (because they are suffixed with UL and the value
0x80000000 fits in a unsigned long int, i.e. a 32-bit value). When
summing them up, the result overflows the maximum value that can be
encoded in a 32-bit value so it wraps around and does not result in
the expected value.

This patch changes the suffix of these constants into ULL so that they
always are 64-bit values.
