soc/mediatek/mt8186: Modify internal capid to 0xE0
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.
