spi: pxa2xx: Apply CS clk quirk to BXT ...
[ Upstream commit 6eefaee4f2d366a389da0eb95e524ba82bf358c4 ]
With a couple allies at Intel, and much badgering, I got confirmation
from Intel that at least BXT suffers from the same SPI chip-select
issue as Cannonlake (and beyond). The issue being that after going
through runtime suspend/resume, toggling the chip-select line without
also sending data does nothing.
Add the quirk to BXT to briefly toggle dynamic clock gating off and
on, forcing the fabric to wake up enough to notice the CS register
change.
