[PATCH v3 2/2] drivers: cleanup Kconfig stuff

[Felipe Contreras <felipe.contreras@gmail.com>]

Add missing dependencies, and remove redundant ones, and select sensible
defaults.

This is more user-friendly, and logical.

 - TWL4030_CORE people should be able to compile without ARM
 - REGULATOR_TWL4030 if TWL4030_CORE and REGULATOR, it's pretty clear we
   want this
 - USB_GADGET_SELECTED is already inside USB_GADGET
 - USB_GADGET_OMAP only works on ARCH_OMAP1, and USB_OTG_UTILS is
   already selected by NOP_USB_XCEIV
 - USB_GADGET_R8A66597 is meant for ARCH_SHMOBILE
 - USB_MUSB_HDRC needs either NOP_USB_XCEIV, or TWL4030_USB
 - USB_MUSB_AM35X, NOP_USB_XCEIV is already selected because MACH_OMAP3EVM

Finally, move:
config USB_MUSB_HDRC
	select NOP_USB_XCEIV if (ARCH_DAVINCI || MACH_OMAP3EVM || BLACKFIN)
	select TWL4030_USB if MACH_OMAP_3430SDP

To:
config TWL4030_USB
	default y if ARCH_OMAP3

config NOP_USB_XCEIV
	default y if ARCH_DAVINCI || MACH_OMAP3EVM || BLACKFIN
