The programming of the HW command FIFO in ccree was done via
a set of macros which suffer a few problems:
- Use of macros rather than inline leaves out parameter type
  checking and risks multiple macro parameter evaluation side
  effects.
- Implemented via hand rolled versions of bitfield operations.

This patch refactors the HW command queue access into a set
of inline functions using generic kernel bitfield access
infrastructure, thus resolving the above issues and opening
the way later on to drop the hand rolled bitfield macros
once additional users are dropped in later patches in the
series.

Clean up the helper functions used to implement "dump_granted_max" in
debugfs.

Replace the lprocfs_rd_uint() and lprocfs_wr_uint() generic callbacks
with a simpler, more direct implementation of ldlm_rw_uint_fops.

There's a slight change in lustre debugfs write semantics: Using kstrtox
causes EINVAL when the written number is followed by other (garbage)
characters, whereas previously the garbage would be ignored and such a
write would succeed.
