When run meminfo command, it's displayed wrong memory information.
Because some boards are that gd->ram_size is reassigned to other value
in board file.
Additionally, display a memory bank information.
On 4G RPI4 target
- Before
U-Boot> meminfo
DRAM: 948MiB
- After
U-Boot> meminfo
Bank #0: 0 948 MiB
Bank #1: 40000000 2.9 GiB
Bank #2: 0 0 Bytes
Bank #3: 0 0 Bytes
DRAM: 3.9GiB

- Update commit-msg
- Revert common/board_f.c modification. Instead, add codes in mem.c
