arm64: dts: exynos: gs101: allow stable USB phy Vbus detection

Browse Source 
For the DWC3 core to reliably detect the connected phy's Vbus state, we
need to disable phy suspend.

Add
    snps,dis_u2_susphy_quirk
    snps,dis_u3_susphy_quirk
to do that.

While at it, also add
    snps,has-lpm-erratum
as this is set downstream which implies that the core was configured
with LPM Erratum. We should do the same here.
