7d3ac5c779 ptp_pch: eliminate a number of sparse warnings
This fixes a number of sparse warnings like:
  warning: incorrect type in argument 2 (different address spaces)
    expected void volatile [noderef] <asn:2>*addr
    got unsigned int *<noident>

  warning: Using plain integer as NULL pointer

Additionally this fixes a warning from checkpatch.pl like:
  WARNING: sizeof pch_param.station should be sizeof(pch_param.station)
