CONFIG_NR_DRAM_BANKS: Remove unreferenced code as its always defined 

Since commit 86cf1c8285 ("configs: Migrate CONFIG_NR_DRAM_BANKS") &
commit 999a772d9f ("Kconfig: Migrate CONFIG_NR_DRAM_BANKS"),
CONFIG_NR_DRAM_BANKS is always defined with a value (4 is default).
It makes no sense to still carry code that is guarded with
"#ifndef CONFIG_NR_DRAM_BANKS" (and similar). This patch removes
all these unreferenced code paths.
