arm64: dts: mt8195-cherry-tomato: change watchdog reset boot flow
The external output reset signal was originally disabled and sent from
firmware. However, an unfixed bug in the firmware on tomato prevents
the signal from being sent, causing the device to fail to boot. To fix
this, enable external output reset signal to allow the device to reboot
normally.

4b4e050842 arm64: dts: mediatek: cherry: Add external codecs and speaker amplifier
The entire Cherry family has two digital microphones, for which
we use the generic dmic-codec, linked to the MT6359 PMIC.
Moreover, it uses a Realtek RT1019p amplifier for the speakers
and has either a Realtek RT5682i or RT5682s audio codec on I2C2:
specifically, RT5682i is found on Tomato's rev 1 and rev 2 boards,
while RT5682s is found in rev3 and rev4 boards.

10d4a706ff arm64: dts: mediatek: cherry: Add I2C-HID touchscreen on I2C4
This platform carries a HID compatible I2C touchscreen on the i2c4 bus,
but it may be at a different address, depending on the board model.
Add the node for a touchscreen at 0x10, but enable it only in the
final board dts.
