We don't need to notify the bus reset for class driver if the non-control
endpoints are not enabled. It could cause unnecessary disconnect event for
android due to below two reasons:
- Android declares the disconnect event for reset handler.
- The controller will get two reset interrupts at HS mode
it fixed two below oops:

pll BYPASS bit should be kept inside pll driver for glitchless freq
setting following spec. If exposing the bit, that means pll driver and
clk driver has two paths to touch this bit, which is wrong.

So use EXT_BYPASS bit here.

And drop uneeded set parent, because EXT_BYPASS default is 0.

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.

According to PLL1443XA and PLL1416X spec,
"When BYPASS is 0 and RESETB is changed from 0 to 1, FOUT starts to
output unstable clock until lock time passes. PLL1416X/PLL1443XA may
generate a glitch at FOUT."

So set BYPASS when RESETB is changed from 0 to 1 to avoid glitch.
In the end of set rate, BYPASS will be cleared.

When prepare clock, also need to take care to avoid glitch. So
we also follow Spec to set BYPASS before RESETB changed from 0 to 1.
And add a check if the RESETB is already 0, directly return 0;
