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.
