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.
