configs: rpi: set NR_DRAM_BANKS to 8 to accommodate RAM on 16GB models
Raspberry Pi 5 can now have up to 16 GiB of RAM where the memory spans 8
DRAM banks in total. Increase the config value to 8 to initialize the
whole RAM. Without this change, kernel only sees 8 GiB of RAM on the 16
GiB CM5 as reported in [1].
