Hide the device so that Windows does not warn about a missing driver.
Tested on system76/lemp10:
- EC functionality remains functional on Linux 5.18.6 and Windows 10.
- Windows 10 does not report the device in Device Manager.

Add a new config for boards with dGPUs to enable reporting fan duty and
temperature. The dGPU is not yet enabled on any boards, so it always
reports the temp as 0. However, the EC firmware does use the dGPU's fan
and so reports valid information for fan speed.

When the EC is reset on PLTRST this information will be lost, causing
system control interrupts to potentially stop functioning.

These fields were originally added for compatibility with the
proprietary ITE EC firmware, but the System76 EC firmware does not use
them. Take the opportunity to document most of the fields as well.

This adds support for line-buffered console output to System76 EC firmware.
Once the print command is received, the EC firmware multiplexes the output
to any enabled console on the EC. This can be a memory ringbuffer, a
parallel port (using the keyboard connector), or i2c (using the battery
connector). Once the entire buffer is sent, it sets the command register
to 0, indicating completion. For more information, please see:
https://github.com/system76/ec/blob/master/doc/debugging.md
Tested on system76/lemp9 with CONSOLE_SYSTEM76_EC enabled.
