[Buildroot] [PATCH v1 0/2] Raspberry Pi 4 - mesa3d support

[Peter Seiderer]

Add Raspberry Pi 4 - mesa3d support, enables hardware supported
graphic output for RPi4 64bit using mesa3d.

Tested by adding DTB overlay 'dtoverlay=vc4-fkms-v3d' to config.txt and
running the following commands:

	$ QT_LOGGING_RULES="qt.qpa.*=true" /usr/lib/qt/examples/gui/analogclock/analogclock

	$ QT_LOGGING_RULES="qt.qpa.*=true" /usr/lib/qt/examples/quickcontrols/controls/gallery/gallery
