HWINFO has a bit (bit 6) which tells you whether retention is supported,
it's in all TRMs since OMAP3630 or so.
"6 RERETMODE Retention mode generic parameter
This bit field indicates whether the
retention mode is supported using the
pin PIRFFRET.
0x0: Retention mode disabled
0x1: Retention mode enabled"
