ENGR00229665 pxp: correct crop setting

The settings in the PXP_PS_BUF, PXP_OUT_PS_ULC, and PXP_OUT_PS_LRC will
determine the subset of the PS buffer, or clipped PS source buffer, that
will be used in the output buffer.

HW_PXP_OUT_PS_LRC should set the scaled output size rather than the origin
size when scaling.

Please refer to the "Clipping source images" section in RM for how it works.
