ARM: OMAP5: Add minimal support for OMAP5430 SOC
OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP
architecture. It's a dual core SOC with GIC used for interrupt
handling and with an integrated L2 cache controller.
OMAP5432 is another variant of OMAP5430, with a
memory controller supporting DDR3 and SATA.
Patch includes:
- The machine specific headers and sources updates.
- Platform header updates.
- Minimum initialisation support for serial.
- IO table init
