AMD's fixed MTRRs have RdDram and WrDram bits that route memory
accesses to DRAM vs. MMIO. These are typically hidden for normal
operation by clearing SYS_CFG[19] (MtrrFixDramModEn). According to
BKDGs and AMD64 Programmer's Manual vol 2, this bit is clear at
reset, should be set for configuration during POST, then cleared for
normal operation.
Attempting to modify the RdDram and WrDram settings without unhiding
them causes a General Protection Fault. Add functions to enable and
disable MtrrFixDramModEn. Unhide/hide as necessary when copying or
writing the fixed MTRRs.
Finally, modify sipi_vector.S to enable the bits prior to writing
the fixed MTRRs and disable when complete.
This functionality is compiled out on non-AMD platforms.

The USBHID driver zero-initializes some but not all of the fields in its
usbhid_inst_t structure. This is a problem because under some
circumstances, some of the uninitialized fields may be read and lead to
incorrect behavior. Some (broken) USB keyboards keep sending reports
that contain all zeroes even when they have no new keys... these usually
get silently ignored, but if the usbhid_inst_t structure is in an
inconsistent state where 'previous' is zeroed out but 'lastkeypress'
is non-zero because it wasn't properly initialized, these reports will
be interpreted as keyrepeats of the bogus 'lastkeypress'. This patch
changes the code to just xzalloc() the whole structure so we won't have
to worry about initialization issues anymore.
