avr32: Rework SDRAM initialization code
This cleans up the SDRAM initialization and related code a bit, and allows faster booting. * Add definitions for EBI and internal SRAM to asm/arch/memory-map.h * Remove memory test from sdram_init() and make caller responsible for verifying the SDRAM and determining its size. * Remove base_address member from struct sdram_config (was sdram_info) * Add data_bits member to struct sdram_config and kill CFG_SDRAM_16BIT * Add support for a common STK1000 hack: 16MB SDRAM instead of 8.
