[PATCH v2 4/7] drm/rockchip: dw_hdmi: Set cur_ctr to 0 always

[Jonas Karlman]

From: Douglas Anderson <dianders at chromium.org>

Jitter was improved by lowering the MPLL bandwidth to account for high
frequency noise in the rk3288 PLL.  In each case MPLL bandwidth was
lowered only enough to get us a comfortable margin.  We believe that
lowering the bandwidth like this is safe given sufficient testing.
