uhci: Increase bulk transfer STACKTDS to 16

Increase the number of simultaneous transfer descriptors that the
driver will build for uhci.  The old value of 4 was a leftover from
when SeaBIOS had a tiny 512 byte extra stack - now that there is a 2K
extra stack there is plenty of space for additional descriptors.
Using a value of 16 should allow for an entire 1ms frame of bulk
transfer content to be setup in advance (assuming the max packet size
is 64 bytes).
