Subject: [PATCH v6 03/54] clk: mediatek: Migrate to mtk_clk_pdev_probe() for multimedia clocks

Reduce duplication and simplify all MediaTek multimedia clock drivers
by migrating away from defining custom probe functions for each driver
and instead use mtk_clk_pdev_probe().

While at it, also add a .remove() callback to all of the multimedia
clock drivers where missing.
