soc/intel/common/block/gspi: set cs polarity before using

Move call to __gspi_cs_change() in gspi_ctrlr_setup() to after
initialization of cs polarity since it requires polarity to be
set to work properly.  Failure to do so confuses cr50.

BUG=b:70628116
BRANCH=chromeos-2016.05
TEST='emerge-meowth coreboot' and verify on scope that chip select
polarity is correct for the first transaction.
