In 2020, geeksville had a NRF52840-dk development board with a
busted oscilliator. Let's retire it from service :)

The lora-relay boards were important pathfinders for nrf52
support some years back. They are no longer commonly produced and
there are now many nrf52 options on the market. Retire these
boards and associated variant.
* Enabling Ve pin on T114
Problem:
The Ve pin was not enabled in the firmware, and it was supposed to control the power to the GPS via the GPS_EN pin. As a result, users were forced to rely on the 3.3V pin to power their additional peripherals, which caused a constant power draw from the battery, even when the node was in deep sleep mode.
Solution:
To resolve this, Todd_Hervert and I decided to remove the GPS power toggle after testing revealed that the GPS only consumes 1mA in soft sleep mode. This minimal power consumption allowed us to enable the Ve pin without causing significant battery drain. Additionally, we added a delay to the I2C initialization process, as the Ve pin requires a few milliseconds to stabilize, which could prevent some peripherals from booting up in time.
Result:
The GPS operates as usual, drawing only 1mA of power.
The keyboard and other peripherals attached to the Ve pin now power off correctly when the node is shut down.
The I2C check initiates without issues after the delay, allowing all peripherals to function smoothly.

* Honor TFT_MESH color if defined for Heltec T114 or T190
* Temporary: point lib_deps at fork of Heltec's ST7789 library
For demo only, until ST7789 is merged
* Update lib_deps; tidy preprocessor logic
As reported by @eureekasigns and @GPSFan, Chatter 2 had begun
to show a blank screen on boot after recent TFT display changes.
Setting TFT_BACKLIGHT_ON LOW resolves the issue.
