Revisions 1.0 and 1.1 of the PinePhone mainboard do not have an external
resistor connecting HBIAS to MIC2P. Enable the internal resistor to
provide the necessary headeset microphone bias.

All revisions of the PinePhone share most of the hardware.
This patch makes it easier to detect PinePhone hardware without
having to check for each possible revision.

All revisions of the PinePhone have an SGM3140 LED flash. The gpios were
swapped on v1.0 of the board, but this was fixed in later revisions.

At the moment PinePhone comes in two slightly incompatible variants:
- 1.0: Early Developer Batch
- 1.1: Braveheart Batch
There will be at least one more incompatible variant in the very near
future, so let's start by sharing the dtsi among multiple variants,
right away, even though the HW description doesn't yet include the
different bits.
The differences between 1.0 and 1.1 are: change in pins that control
the flash LED, differences in modem power status signal routing, and
maybe some other subtler things, that have not been determined yet.
This is a basic DT that includes only features that are already
supported by mainline drivers.
