The clk_stub, regulator, and pinctrl fixes enable the sdcard on the RB5
dev board (and sm8250 devices broadly). clk_stub is only enabled in
qcom_defconfig and the others are qcom specific so these shouldn't
affect other platforms.

Lastly, a small ufetch fix from Sam which gets color rendering correctly
on U-Boots framebuffer video device.
