zephyr: add support for bc1.2 in device tree
This commit adds support for bc1.2 definition in device tree.
It will allow to remove board specific files which implemented
the bc1.2 functionalities. This will unify the logic between
different board in zephyr.
BRANCH=main
BUG=b:194432779
TEST=HOST MODE: Plug non-pd device into TypeC port and verified that the
device received power and the following was printed to
the EC console: pi3usb9201[p0]: CDP_HOST mode]
CLIENT MODE: Plug an non-pd TypeC charger into the DUT and verified
that the device was charging with the "chgsup"
command. The EC console displayed the following:
port=0, type=1, cur=3000mA, vtg=5000mV, lsm=1
And the following debug output was displayed:
pi3usb9201[p0]: sts = 0x80, lim = 1500 mA, supplier = 3]
Using Suzy-Q, EC console displayed the follow:
pi3usb9201[p0]: sts = 0x40, lim = 500 mA, supplier = 5]
and "chgsup"
port=0, type=2, cur=1500mA, vtg=5000mV, lsm=1
Same results on Port 1
