Julius Werner 57ddd9abc7 libpayload: usb: xhci: Count new Max Scratchpad Bufs bits from XHCI 1.1
The 1.1 revision of the XHCI specification added an extra 5 bits to the
Max Scratchpad Bufs field of HCSPARAMS2 that newer controllers make use
of. Not honoring these bits means we're not allocating as many
scratchpad buffers as the controller expects, which means it will
interpret some uninitialized values from the end of the pointer array as
scratchpad buffer pointers, which obviously doesn't end well. Let's fix
that.

BRANCH=none
BUG=chrome-os-partner:42279
TEST=Makes a USB-related memory corruption issue disappear.
