[PATCH v2] ARM: dts: sun5i: q8-common: Enable USB-based WiFi

[wens@csie.org (Chen-Yu Tsai)]

The early A13 Q8 tablets all use a Realtek WiFi module connected to
USB1. The module is powered by AXP209's LDO3 at 3.3V.

Move the related settings from sun5i-a13-q8-tablet.dts to
sun5i-q8-common.dtsi, for all q8-based tablets.
