2022-03-10soc/mediatek/mt8186: Modify internal capid to 0xE0Rex-BC Chen
The mainboard may not be able to disable the internal cap, so we want to set 0xe0 for all boards to minimize the internal cap. And a mainboard implementation may choose XTAL with higher cload if the frequency requirement is met, and the total capacitance can be tuned externally for different boards. BUG=b:218439447 TEST=set capid to 0xe0.

2022-03-02soc/mediatek/mt8186: Set RTC capid to 0xC0 to pass XTAL 26 MHz testRex-BC Chen
The XTAL 26MHz test failed on krabby, so we adjust RTC capid from default value 0x88 to 0xC0 for MT8186. We also add a new log message to show the capid value which is read from MT6366. This implementation is according to chapter 5.13 in MT8186 Functional Specification. BUG=b:218439447 TEST=set capid to 0xc0. TEST=XTAL 26MHz test passed.
