PI3USB9238: Read device type and charge registers after INTB assertionstabilize-11647.70.Bstabilize-11647.104.Brelease-R73-11647.B
PI3USB9238 can fail to detect BC 1.2 charger because the initialization
timing after reset differs chip to chip.
This patch checks the interrupt register in a loop to wait until device
type and charger status registers are ready.

BUG=b/119166282
BRANCH=nami
TEST=Verify BC 1.2 chargers are reliably detected as
DCP (wall-charger), CDP (type-A port on chromebook),
and SDP (type-c port on chromebook) by type-c port of Vayne
(via A-to-C cable).
