omap4: utility function to identify the context of hw init
The basic hardware init of OMAP4(s_init()) can happen in 4
different contexts:
1. SPL running from SRAM
2. U-Boot running from FLASH
3. Non-XIP U-Boot loaded to SDRAM by SPL
4. Non-XIP U-Boot loaded to SDRAM by ROM code using the
Configuration Header feature
What level of hw initialization gets done depends on this
context. Add a utility function to find this context.
