turn off peripherals before deep sleep (fixes #1493)

similar to RAK's PIN_3V3_EN, we need to enable in setup() and disable before deep sleep/shutdown.

also:

  • renames PIN_EINK_PWR_ON to PIN_POWER_EN to match LilyGO's pin map.
  • removes T-Echo peripheral power on from EInkDisplay2

@pista01 can you please test the .uf2 in the zip below and check if your T-Echo works without the boot loop issue?
