PATCH v3 1/1 dts: Minimal device tree for Quanta Q71L BMC

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
Changes in v3:
- Remove opp prefix from dts filename as this is not an OpenPower machine
