[PATCH] remove check_region from isdn_hisax_s0box.c

  This patch for isdn/hisax/s0box.c driver for Linux removes one call to
  check_region using request_region instead.

  I don't have this hardware so I hope I got it right.  This patch
  removes all references to check_region in this driver.

  This is patch number 14 in a series of check_region patches I am doing as
  part of the kernel janitors project.
