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.

The AUDIO PLL max support 650M, so the original clk settings violate
spec. This patch makes the output 786432000 -> 393216000,
and 722534400 -> 361267200 to aligned with NXP vendor kernel without any
impact on audio functionality and go within 650MHz PLL limit.

This is enabled by default but if it's not explicitly defined and marked
as critical then its parent might get turned off.

* Replace to audio_pll2_clk with audio_pll2_out
* Replace sys3_pll2_out with sys_pll3_out
* Replace sys1_pll_40m with sys_pll1_40m
* qspi parent[2] is sys_pll2_333m not sys_pll1_800m
