zephyr: trogdor: Create Zephyr image for trogdor
Trogdor is a reference design, which doesn't have Zephyr support yet.
Lazor is a shipping design of the Trogdor family, which already have
Zephyr support. This CL creates the Trogdor Zephyr image and modifies
the hardware difference.
The CL first copies the directory lazor/ to trogdor/.
And do the following changes:
* Rename all the board term lazor -> trogdor
* Update the GPIOs (recheck the result of gpios_to_zephyr_dts)
* Update the GPIO interrupts
* Update the battery info
* Update the sensor info
* Do not support multi-TCPM driver
* Do not include sku.c (trogdor doesn't have it yet)
BRANCH=None
BUG=b:184071830
TEST=Built the Zephyr image. Booted it on an existing Trogdor board.
