Evan Green 6eefaee4f2 spi: pxa2xx: Apply CS clk quirk to BXT ... 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.
