spi: pxa2xx: Add support for Intel Cannonlake

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.
