libpayload: usb: Allow direct instantiation of MMIO host controllers

Browse Source 
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.
