Some Chromebooks (with Baytrail CPUs) apparently do not support

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.
We just fixed this in libpayload and it seems to apply the same way to
SeaBIOS (I only compile-tested this, though... sorry).

mptable: Don't create mptable if it is very large
Very large mptable structures can fill up the space in the f-segment
and cause other important f-segment allocations to fail. Limit the
maximum size of the mptable to prevent this.
On QEMU, with the current maximum size of 600 bytes, the mptable will
not be created in configurations of ~20 cpus or more. The mptable is
rarely used in modern OSes so this should not be a problem.

ps2: Don't wait 100ms to discard possible extra reset receive byte
The existing PS2 port code waits 100ms to see if the device attached
to the keyboard port responds to a reset command with two bytes
(instead of the normal one byte). If an extra byte is received, it is
discarded.
Receiving two bytes would be unusual and waiting to check for that
event is unnecessary because the next command in the keyboard init
sequence already seamlessly discards any extra bytes in the command
queue.
This patch eliminates the 100ms wait, which notably reduces the
SeaBIOS boot time on QEMU. This patch also forces PS2 mice to always
respond with two bytes during a reset sequence (instead of just one
byte), which is a good sanity check.
