[PATCH linux v2] dts: Minimal device tree for Quanta Q71L BMC

[Rick Altherr]

Supports:
  - BMC console UART
  - BMC boot flash
  - host boot flash
  - host virtual UART (host console)

--
Changes in v2:
 - Reserve correct VGA framebuffer location in RAM
 - Remove pinctl settings for FLBUSY and FLWP as Q71L uses those pins as
   GPIOs
 - Enable I2C masters used by Q71L
