arm: mach-omap2: Pass args to secure ROM in SRAM in SPL

Browse Source 
When in early SPL we make some secure ROM calls that can effect
DRAM, due to this it is more stable to store the args for these
calls in SRAM, but uninitialized and zero'd globals are placed
in BSS, located in DRAM. Force our args into the data section
which is in SRAM during SPL.
