This commit fixes the incorrect memory (FLASH and SRAM) size
specification in the device tree and the board test yaml files.
The `qemu_cortex_r5` board (using `fdt-single_arch-zcu102-arm.dtb` FDT)
has 64MiB RAM at the address 0 and 32MiB QSPI flash at 0xc0000000.
QEMU `info mtree`:
0000000000000000-ffffffffffffffff (prio 0, i/o): memory@00000000
0000000000000000-000000000002ffff (prio 0, ram): ddr_bank1_1@0x0
0000000000030000-000000000003ffff (prio 0, ram): ddr_bank1_2@0x30000
0000000000040000-0000000003ffffff (prio 0, ram): ddr_bank1_3@0x40000
00000000c0000000-00000000c1ffffff (prio 0, i/o): lqspi
