[PATCH v3 33/46] media: rkisp1: isp: Merge ISP_ACQ_PROP configuration in single variable

[Laurent Pinchart]

The rkisp1_config_isp() function stores the value of the input selection
and polarity configuration in two different local variables, OR'ed
together when writing the register. Merge them into a single acq_prop
variable.
