Subject: [PATCH 5.4 17/20] csky: change a Kconfig symbol name to fix e1000 build error

From: Randy Dunlap <rdunlap@...radead.org>

[ Upstream commit d199161653d612b8fb96ac51bfd5b2d2782ecef3 ]

e1000's #define of CONFIG_RAM_BASE conflicts with a Kconfig symbol in
arch/csky/Kconfig.

The symbol in e1000 has been around longer, so change arch/csky/ to use
DRAM_BASE instead of RAM_BASE to remove the conflict.  (although e1000
is also a 2-line change)
