[PATCH RFC u-boot-mvebu 57/59] arm: mvebu: Define env_sf_get_env_addr() also for Proper U-Boot

Proper U-Boot moves SPI0 CS0 Flash mapping from 0xD4000000 to 0xF4000000
and change its size from 64 MB to 8 MB. Definitions are already in
MBUS_SPI_BASE/MBUS_SPI_SIZE macros. So define these macros also for SPL
build, use them in env_sf_get_env_addr() function and move this function
from spl.c to cpu.c to be available in Proper U-Boot too.
