zephyr: Fix I2C_PASSTHRU host command
ZephyrEC uses different I2C port numbers than CrosEC does, so convert
the received remote port via I2C_PASSTHRU command into a proper one.
The conversion is done based on a new property remote-port, which tells
what port number is used by external components like kernel.
The change fixes an issue with unexpected entering OTG mode by the
charger.
BUG=b:188885798
BRANCH=none
TEST=Flash Lazor and make sure that no "charge problem" prints are
displayed.
