drm/msm/dsi: fix wrong type in msm_dsi_host

[ Upstream commit 409af447c2a0a6e08ba190993a1153c91d3b11bd ]

Change byte_clk_rate, pixel_clk_rate, esc_clk_rate, and src_clk_rate
from u32 to unsigned long, since clk_get_rate() returns an unsigned long.

Fixes: a6bcddbc2ee1 ("drm/msm: dsi: Handle dual-channel for 6G as well")
