Trogdor: Initial board commit

This is an initial commit for Trogdor. Use Cheza as a baseline.

Make the change according to the schematic, e.g.
 * Reflect the GPIO change
 * Reflect the TCPC/PPC part change
 * Update the USB topology, e.g. no device mode support
 * Remove the detachable related code
 * Add keyboard support
 * Support keyboard backlight
 * Update the battery characteristic
 * Add initial support of muxing DP path
 * Support a single USB-A port
 * Change sensors from lid to base
 * Minor code style improvement
