scb9328: Add ARM relocation support 

This patch fixes compiler errors due to missing definitions of
CONFIG_SYS_SDRAM_BASE and CONFIG_SYS_INIT_SP_ADDR.

It also does some cleanup: CONFIG_SYS_TEXT_BASE was moved to scb9328.h,
obsolete config.mk was removed. The scb9328 board has 1 DRAM bank, so don't
ask for more banks. CONFIG_NR_DRAM_BANKS will ever be 1.

# You might change location of U-Boot in memory by setting right CONFIG_SYS_TEXT_BASE.
# This allows for example having one copy located at the end of ram and stored
# in flash device and later on while developing use other location to test
# the code in RAM device only.
