[PATCH 05/10] ARM: i.MX6: esdctl: Use symbolic constants for RAM base address

[Andrey Smirnov]

Use symbolic constants for RAM base address, to do that rename
MX6_MMDC_PORT0_BASE_ADDR to MX6_MMDC_PORT01_BASE_ADDR to distinguish
it from SoCs with only one DDR controller (i.MX6UL) where port 0 will
always be at 0x80000000.
