Current handling of the keyboard polling was very slow and
keys were getting dropped. Done following for fixing this:
* Use multiple buffers per TRB
* Allocate buffers in xhci according to the number of TRBS.
This reduces the delay of key? processing by getting rid of wait in
the polling routine.

commit 706c69e4 "xhci: fix port assignment" partially fixed the
usb port numbering.
Adding parsing of xhci extended capabilities, we can parse the
overlapped ports accordingly and have proper port numbering.
