DM USB: xHCI: refine xHCI extended capability related functions.

Browse Source 
Every platform should have their own xHCI specific extended
capabilities, but the current xHCI DM is not scalable for them. This
patch refines related logic to make it scalable.

Current code only support 4 registers(4*32) as basic extended
capabilites. Base on this new implementation, the mmio range from
excapoff to regsend will cover real excap size according to the cap
parameter.
