   changes from v1 to v2:
 	- Add Reviewed-by tag from v1 result
 	- Split out the changes for dt-bindings .h from the changes for driver
 	- Fix up the typo in g3dsys dt-bindings documentation

Hi,

The series adds a required resource setup to allow Mali-450 to work on
MT7623. This also can benefits other MediaTek SoCs having Mali-450 device.

In order to prove the setup is proper, I also have added mediatek port to
linux-lima at [1] and make a few of tests along with off-screen rendering
[2][3][4][5][6][7] through mesa-lima [8]. All work correctly.

[1] https://github.com/objelf/linux-lima/tree/mediatek-lima-4.16-rc5
[2] simple triangle: https://github.com/yuq/gfx/tree/master/gbm-surface
[3] vertex shader uniform: https://github.com/yuq/gfx/tree/master/gbm-surface-move
[4] multi varying: https://github.com/yuq/gfx/tree/master/gbm-surface-color
[5] multi draw: https://github.com/yuq/gfx/tree/master/gbm-surface-draw
[6] FBO: https://github.com/yuq/gfx/tree/master/gbm-surface-fbo
[7] kmscube: https://github.com/yuq/kmscube
[8] https://github.com/yuq/mesa-lima

Hope these patches can help people working on BPI-R2.

	Sean
