PHY: sunxi: Add driver for sunxi usb phy

The Allwinner A1x / A2x SoCs have 2 or 3 usb phys which are all accessed
through a single set of registers. Besides this there are also some other
phy related bits which need poking, which are per phy, but shared between the
ohci and ehci controllers, so these are also controlled from this new phy
driver.

spi: sun4i: Set bits_per_word_mask to only support 8 bits word length

This controller only supports 8 bits word length.
Set bits_per_word_mask so spi core will reject transfers that attempt to use
an unsupported bits_per_word value.

ARM: sunxi: dt: Add sunxi-common-regulators include file

Most sunxi boards with a sata connector also have a gpio controlled connector
for sata target power and almost all sunxi boards have a gpio controlled vbus
for usb1 and usb2.

This commit adds an include file for the regulators representing these
supplies, avoiding the need to copy and paste the regulator code to allmost
all sunxi board dts files.

ARM: sun4i: dt: Add ahci / sata support

This patch adds sunxi sata support to A10 boards that have such a connector.
Some boards also feature a regulator via a GPIO and support for this is also
added.

ARM: sun4i: dt: Add USB host nodes to hackberry dts

Add nodes for the usb-phy and ehci- and ohci-usb-host controllers.

Based on fex file settings, the fex file also contains a mysterious line:
usb_hub_vcc_en_gpio = port:PB09<1><0><default><0>

Which also clashes with usbc0, which has:
usb_drv_vbus_gpio = port:PB09<1><0><default><0>

So if usb does not work properly we need someone with a hackberry to look
closer into this.
