krane: add it5205 driver
An it5205 is added in kukui/krane rev 5, and deprecated gpio pin
USB_C0_DP_OE_L and USB_C0_DP_POLARITY.
This CL is intended to make the fw works for both old and new boards:
1) the default usb_mux driver is updated to rev 5, and board_rev_init
may change it back for old boards.
2) keep VARIANT_KUKUI_DP_MUX_GPIO in kukui/board.h, and add a customized
function to set/clear these gpio pins.
BUG=b:135079572
TEST=verify that type c display works on board rev 4/5
BRANCH=master
