ARM: OMAP2: AM33XX: id: Add support for new AM335x PG2.1 Si

Add support for chip id detection of AM335x PG2.1 Silicon. Currently omap3xxx_check_revision() detects PG1.0 and PG2.0 only, this patch extends it by adding PG2.1 Si support. Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
