When registering the PLL, unbypass the PLL.
The PLL has two bypass control bit, BYPASS and EXT_BYPASS.
we will expose EXT_BYPASS to clk driver for mux usage, and keep
BYPASS inside pll14xx usage. The PLL has a restriction that
when M/P change, need to RESET/BYPASS pll to avoid glitch, so
we could not expose BYPASS.
To make it easy for clk driver usage, unbypass PLL which does
not hurt current function.
