According to Synopsys DW MIPI DSI host databook, HSTX and LPRX timeout
contention detections are measured in TO_CLK_DIVISION cycles.  However,
the current driver programs magic values to TO_CLK_DIVISION, HSTX_TO_CNT
and LPRX_TO_CNT register fields, which makes timeout error event wrongly
happen for some video modes, at least for the typical 1920x1080p@60 video
mode read from a HDMI monitor driven by ADV7535 DSI to HDMI bridge.
While at it, the current driver doesn't enable interrupt to handle or
complain about the error status, so true error just happens silently
except for display distortions by visual check.

Disable the timeout check by setting those timeout register fields to
zero for now until someone comes along with better computations for the
timeout values.  Although the databook doesn't mention what happens when
they are set to zero, it turns out the false error doesn't happen for
the 1920x1080p@60 video mode at least.
