libpayload: usb: Allow direct instantiation of MMIO host controllers

The existing USB_MEMORY mechanism to instantiate non-PCI host
    controllers is clunky and inflexible... most importantly, it doesn't
    allow multiple host controllers of the same kind. This patch replaces it
    with a function that allows payloads to directly instantiate as many
    host controllers of whatever type they need.
