[PATCH v6 01/10] CONFIG_NR_DRAM_BANKS: Remove unreferenced code as its always defined

Mon Aug 17 08:48:40 CEST 2020
Since commit 86cf1c82850f ("configs: Migrate CONFIG_NR_DRAM_BANKS") &
commit 999a772d9f24 ("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.

(no changes since v5)
Changes in v5:
- Add Reviewed-by tag from Pali & Andy
- Move "bd" assignment as suggested by Andy
Changes in v4:
- Only remove dead code with CONFIG_NR_DRAM_BANKS always defined
