[PATCH v4 10/17] drm/bridge: cdns-dsi: Update htotal in cdns_dsi_mode2cfg()

[Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>]

cdns_dsi_mode2cfg() calculates the dsi timings, but for some reason
doesn't set the htotal based on those timings. It is set only later, in
cdns_dsi_adjust_phy_config().

As cdns_dsi_mode2cfg() is the logical place to calculate it, let's move
it there. Especially as the following patch will remove
cdns_dsi_adjust_phy_config().
