soc/intel/xeon_sp: Move proximity domain setting up

Move proximity domain setting up to ahead of attach_iio_stacks()
so that proximity domain info could be ready before
attach_iio_stacks()/create_xeonsp_domains().

For example in SPR, is_iio_cxl_stack_res() refers to proximity
domain info, and it will be called in create_xeonsp_domains().

TEST=Build and boot on intel/archercity

No significant boot log difference except for proximity domain
dump info display are moved ahead (with correct contents).
