Best to keep the dts entry as is and add quirk handling to ti-sysc driver
instead based on mcasp revision register detection. The dts is meant to
describe hardware and the register values exist.. But looking at ti-sysc
we already have mcasp tagged with SYSC_QUIRK_SWSUP_SIDLE.
If this patch is still needed, maybe check the revision register value and
mask in case there are multiple revisions, that's this line in ti-sysc:
SYSC_QUIRK("mcasp", 0, 0, 0x4, -ENODEV, 0x44306302, 0xffffffff,
SYSC_QUIRK_SWSUP_SIDLE),
