These changes add support for MUSB (OTG) and HCI1 on sun50i (A64) and try to improve documentation: * adds support for the shared PHY (MUSB and OTG-EHCI/OTG-OHCI) on sun50i (A64) in musb-new/sunxi.c to automatically change the PHY routing when opening/closing MUSB * sets up the usb_phy_passby only from the HCI ([eo]hci_sunxi.c) init and does not match on the PHY id (id #0 is either used by MUSB or by OTG-EHCI/OHCI) in the common PHY initialisation * adds support for clearing the 'SIDDP' bit in the PHYCTL register (and left a comment for the H3, which apparently does the same from sunxi_usb_phy_config in a 'magic' write) * introduced a SUNXI_MUSB_BASE define for the MUSB driver to find the controller (it's usually USB0_BASE, but not on the A64 where USB0_BASE is the OTG-EHCI/OHCI address space) ... this should eventually disappear entirely, as the sunxi musb support moves to support the device model * added initialisation calls to clearing the 'SIDDP' bit in the PHYCTL register and for the usb_phy_passby to ehci-sunxi.c and ohci-sunxi.c (note that these are idempotent, so we don't need to worry that we call this multiple times) * updated the comments in 'sunxi_usb_phy_config' based on the English comments in Allwinner's 3.10 kernel release * add additional defines for the clock gating and module reset bits for the somewhat different controller configuration in the A64, partially motivated by the fact that the musb-new/sunxi.c glue expects AHB_GATE_OFFSET_USB0 to be the bit number for MUSB.
Note (for testers) that turning on the complete USB hub cascade connected to EHCI1 on the A64-uQ7 requires two GPIOs, so you will need to either have the (separate) change for having multiple GPIOs in your tree or issue the command 'gpio set pe4' to turn on the second (cascaded) hub.
