drm/msm: Remove unneeded semicolon

./drivers/gpu/drm/msm/hdmi/hdmi_phy_8998.c:282:2-3: Unneeded semicolon

This patch removes an unneeded semicolon after a switch statement in the
pll_get_post_div function. Adding a semicolon after a switch statement is
unnecessary and can lead to confusion in the code structure.
