Subject: [PATCH 2/4] davinci-mcasp: use bitfield definitions for PDIR

The current driver creates value for set/clr of PDIR using (x<<26) instead
of the #defines that are convieniently made available.

Update the driver to use the bitfield definitions of PDIR. There is no
functional change introduced by this patch.
