Rockchip 3566/8 SoCs are affected by the GIC integration issue where
GIC reports that it supports programmable shareability in a feature
register, while in fact it doesn't support this feature. Rockchip
assigned Errata ID #3568001 for the issue.

Add dma-noncoherent GIC property, denoting that a SW quirk is required
for the GIC.
