spi: pxa2xx: Add support for Intel Cannonlake

Browse source

Intel Cannonlake LPSS SPI has up to four chip selects per port like in
Broxton and is clocked like Sunrisepoint and Kaby Lake. Add a new type
LPSS_CNL_SSP and configuration that enable runtime chip select detection
and use the same FIFO thresholds than in Sunrisepoint.

Patch adds support for both Cannonlake SoC and PCH.
