cxl/region: Add @hpa_range argument to function cxl_calc_interleave_pos()

cxl_calc_interleave_pos() uses the endpoint decoder's HPA range to
determine its interleaving position. This requires the endpoint
decoders to be an SPA, which is not the case for systems that need
address translation.

Add a separate @hpa_range argument to function
cxl_calc_interleave_pos() to specify the address range. Now it is
possible to pass the SPA translated address range of an endpoint
decoder to function cxl_calc_interleave_pos().

Refactor only, no functional changes.

Patch is a prerequisite to implement address translation.
