drm/hisilicon/hibmc: fix no showing problem with loading hibmc manually
When using command rmmod and insmod, there is no showing in second time
insmoding. Because DP controller won't send HPD signals, if connection
doesn't change or controller isn't reset. So add reset before unreset
in hibmc_dp_hw_init().
And also need to move the HDCP cfg after DP controller de-resets, so
that HDCP configuration takes effect.
