History
Shaun Ruffell aa8bd2f546 wct4xxp: __t4_frame_in and __t4_framer_out slowdowns. 
This is a partial revert of r10234 "wct4xxp: __t4_framer_in and
__t4_framer_out speedups."

There were some platform + firmware version combinations that would fail to
properly configure the framer with the aforementioned speedups. The originally
reported sympton was that interrupts would fail to start and while
troubleshooting I also saw cases where one of the spans would stay in alarm
after starting. By adding in additional reads to the version register, the
overall process of writing / reading from the framer control registers is
slowed down which increases reliability.

This change does *not* affect the main path of TDM data which is DMAed
directly into buffers in host memory and are not read / written to / from
framer registers directly.
