Philip Chen e6c6404cd6 scarlet: Limit the maximal acceptable VBUS to 13V ...

When my 15V/30W charger is plugged in scarlet,
I see rt946x (the battery charger on Scarlet) asserts OVP because
VBUS(15V) > VBUS_OVP(14V) defined in rt946x datasheet.

So we should limit the maximal VBUS to ~13V even if the source can
provide higher voltage.

Meanwhile, let's replace some numbers with macros for better
maintainability.

BUG=b:65118519
BRANCH=none
TEST=manually verify charging works with a 15V/30W PD charger
