Andy Shevchenko f5da0820c5 spi: Assume GPIO CS active high in ACPI case 
[ Upstream commit 6b69546912a57ff8c31061f98e56383cc0beffd3 ]

Currently GPIO CS handling, when descriptors are in use, doesn't
take into consideration that in ACPI case the default polarity
is Active High and can't be altered. Instead we have to use the
per-chip definition provided by SPISerialBus() resource.

Fixes: 766c6b63aa04 ("spi: fix client driver breakages when using GPIO descriptors")
