The USB PHY and DT updates are in 3.15 so it seems pointless to only
enable those USB host drivers.

I've cherry-picked:
3558fe900e8a spi: sunxi: Add Allwinner A31 SPI controller driver
743a46b89a59 spi: sun6i: Set bits_per_word_mask to only support 8 bits word length
d31ad46f58e8 spi: sun6i: Fix define for SUN6I_TFR_CTL_CS_MASK
65918e26069a ARM: dt: sun4i: Add A10 SPI controller nodes
ba4bdc9e1dc0 PHY: sunxi: Add driver for sunxi usb phy
6ab1ce244be3 ARM: sun4i: dt: Add USB host bindings
and made all the above-requested config changes. I hope that's
sufficient.
Ben.
