2022-09-14soc/mediatek/mt8188: Set PLLs to hardware default valuesGarmin Chang
Some PLLs are not used in firmware, so we should keep them as hardware default values. If their modules want to set them, the corresponding drivers should set them in the kernel stage. BUG=b:233720142 TEST=build pass.

2022-09-14soc/mediatek/mt8188: Change vpp_sel default mux for 4k supportGarmin Chang
vpp_sel and ethdr_sel are vdosys clock source select mux. Steps to change to support 4K source: 1. Change vpp_sel source to mainpll_d6 to run at 416MHz. 2. Change ethdr_sel source to univpll_d6 to run at 416MHz. BUG=b:233720142 TEST=build pass.

2022-09-14soc/mediatek/mt8188: Fix some wrong settings for PLLsGarmin Chang
The observed CPU big core frequency is double compared with the current PLL setting. Therefore fix the wrong setting for PLL register APMIXED_ARMPLL_BL. Moreover, we also fix some wrong settings for other PLLs. TEST=CPU frequency of big core CPU is correct and bootup correctly.

2022-09-07soc/mediatek/mt8188: Enable mfgpll properly and fix SPMI muxesJohnson Wang
Some of the pll settings are incorrect, which cause problems in GPU after booting into kernel. - MFGPLL opp_ck_en bit isn't located at MFGPLL_CON1, so we need to fix it to enable MFGPLL properly. - Switch SPMI clock muxes to 260M to avoid kernel hang while probing SPMI kernel driver. TEST=GPU bringup correctly.
