arm: omap3: am35x: Don't mark missing features as present
The Chip Identification register on the am35x family of SoCs has bits 12, 7:5, and 3:2 marked as reserved and are read as zeroes. Unfortunately, on other omap SoCs, a 0 bit means a feature is "Full Use" so the OMAP3_CHECK_FEATURE() macro called by omap3_check_features() will incorrectly interpret those zeroes to mean that a feature is present even though it isn't. To fix that, the feature bits that are incorrectly set (namely, OMAP3_HAS_IVA and OMAP3_HAS_ISP) need to be cleared after all of the calls to OMAP3_CHECK_FEATURE() in omap3_check_features() are made.
