Tom Rini cd6a45a41f Convert CONFIG_USB_OHCI_NEW et al to Kconfig
This converts the following to Kconfig:
    CONFIG_SYS_OHCI_SWAP_REG_ACCESS
    CONFIG_SYS_USB_OHCI_CPU_INIT
    CONFIG_SYS_USB_OHCI_MAX_ROOT_PORTS
    CONFIG_SYS_USB_OHCI_SLOT_NAME
    CONFIG_USB_ATMEL
    CONFIG_USB_ATMEL_CLK_SEL_PLLB
    CONFIG_USB_ATMEL_CLK_SEL_UPLL
    CONFIG_USB_OHCI_LPC32XX
    CONFIG_USB_OHCI_NEW
