usb: phy: omap: Add new device types and remove omap_control_usb3_phy_power()

Browse source 
Add support for new device types and in the process rid of "ti,type"
device tree property. The correct type of device will be determined
from the compatible string instead.

Introduce a compatible string for each device type. At the moment
we support 4 types OTGHS, USB2, PIPE3 (e.g. USB3) and DRA7USB2.

Update DT binding information to reflect these changes.

Also get rid of omap_control_usb3_phy_power(). Just one function
i.e. omap_control_usb_phy_power() will now take care of all PHY types.

OMAP CONTROL USB
Required properties:
- compatible: Should be "ti,omap-control-usb"
- compatible: Should be one of
"ti,control-phy-otghs" - if it has otghs_control mailbox register as on OMAP4.
"ti,control-phy-usb2" - if it has Power down bit in control_dev_conf register
e.g. USB2_PHY on OMAP5.
"ti,control-phy-pipe3" - if it has DPLL and individual Rx & Tx power control
e.g. USB3 PHY and SATA PHY on OMAP5.
"ti,control-phy-dra7usb2" - if it has power down register like USB2 PHY on
DRA7 platform.
- reg : Address and length of the register set for the device. It contains
the address of "control_dev_conf" and "otghs_control" or "phy_power_usb"
depending upon omap4 or omap5.
- reg-names: The names of the register addresses corresponding to the registers
filled in "reg".
- ti,type: This is used to differentiate whether the control module has
usb mailbox or usb3 phy power. omap4 has usb mailbox in control module to
notify events to the musb core and omap5 has usb3 phy power register to
power on usb3 phy. Should be "1" if it has mailbox and "2" if it has usb3
phy power.
the address of "otghs_control" for control-phy-otghs or "power" register
for other types.
- reg-names: should be "otghs_control" control-phy-otghs and "power" for
other types.
