ARM: OMAP3EVM: Adding USB internal LDOs board file
EHCI PHY requires these regulators:
EVM Rev >=E --> VAUX2
EVM Rev < E --> VUSB1V5, VUSB1V8
Adding USB internal LDOs (vusb1v5 & vusb1v8) and VAUX2 to omap3evm
board file. Also removing vaux2_{1/2/3} supplies as they are not
used on omap3 evm.
But we need not to add vaux2 in twl4030_platform_data since it will
be added conditionally.
