Subject: [PATCH] clk: mediatek: Initialize clk flags

The variable init (struct clk_init_data) is allocated on the stack.
We weren't initializing the .flags field, so it contains random junk,
which can cause all kinds of interesting issues when the flags are
parsed by clk_register.

The best solution seems to just pass on the flags passed in to our
clk_register wrappers.
