ARM: OMAP3: Add minimal omap3430 support
Add minimal omap3430 support based on earlier patches from
Syed Mohammed Khasim. Also merge in omap34xx SRAM support
from Karthik Dasu and use consistent naming for sram init
functions.
Also do following changes that make 34xx support usable:
- Remove unused sram.c functions for 34xx
- Rename IRQ_SIR_IRQ to INTCPS_SIR_IRQ and define it locally
in entry-macro.S
- Update mach-omap2/io.c to support 2420, 2430, and 34xx
- Also merge in 34xx GPMC changes to add fields wr_access and
wr_data_mux_bus from Adrian Hunter
- Remove memory initialization call omap2_init_memory() until
until more generic memory initialization patches are posted.
It's OK to rely on bootloader initialization until then.
