[PATCH 09/12] clk: mediatek: move part of mtk_clk_register_gates() to the new function

[Ryder Lee <ryder.lee@xxxxxxxxxxxx>]

In some subsystems, the regmap has already been initialized from its parent,
so there is no need to map it again. To keep flexible, we move some parts to
the new function - mtk_clk_register_num_gates(), and then use it for those
subsystems.
