Changing all of these GRXSTS_PKTSTS defines to use the shifted values
doesn't make any sense, because the one place they are used, a helper
macro is defined that shifts them all back to the right by 17! So, leave
these as they are, and fix the single callsite in s3c-hsotg.c to use the
non-shifted values.

No need to define these DPTXFSIZN macros. Since in patch #2 you are
renaming macro calls in s3c-hsotg.c anyway, just redo the calls to
DPTXFSIZN_DPTXF* to use the existing FIFOSIZE* macros instead. You will
need to add a FIFOSIZE_DEPTH_GET macro to replace DPTXFSIZE_GET.
