This rewrites the Mediatek GNSS bindings in YAML.

ChangeLog v2->v3:
- Add the missed gnss-fix-gpios.
- Move allOf to right before the properties.
- Keep the description on timepulse-gpios because it documents
  which pins are used on this chip.
ChangeLog v1->v2:
- New patch since Krzysztof pointed out there is really just
  one more binding to convert, so why not.

-Mediatek-based GNSS Receiver DT binding

-Mediatek chipsets are used in GNSS-receiver modules produced by several

-
-Please see Documentation/devicetree/bindings/gnss/gnss.txt for generic

-Required properties:
-
-- compatible	: Must be

-			"globaltop,pa6h"
-
-- vcc-supply	: Main voltage regulator (pin name: VCC)

-Optional properties:
-
-- current-speed		: Default UART baud rate

-			  (pin name: FIX, 3D_FIX)
-- reset-gpios		: GPIO used to reset the device (pin name: RESET, NRESET)
-- timepulse-gpios	: Time pulse GPIO (pin name: PPS1, 1PPS)
-- vbackup-supply	: Backup voltage regulator (pin name: VBAT, VBACKUP)

Applied, thanks!

Bindings look good, just the filename should be probably more specific,
to match the model... but then who is the vendor? mediatek,pa6h.yaml or
mediatek,globaltop-pa6h.yaml? I sincerely do not know, so:
