[ Upstream commit f12e0e12524a34bf145f7b80122e653ffe3d130a ]
When dual-DSI (bonded DSI) was added in commit ed9976a09b48 ("drm/msm/dsi: adjust dsi timing for dual dsi mode") some DBG() prints were not updated, leading to print the original mode->clock rather than the adjusted (typically the mode clock divided by two, though more recently also adjusted for DSC compression) msm_host->pixel_clk_rate which is passed to clk_set_rate() just below. Fix that by printing the actual pixel_clk_rate that is being set.
