minios: add tpmfront, tpm_tis, and tpmback drivers

This patch adds 3 new drivers to mini-os.

tpmfront - paravirtualized tpm frontend driver
tpmback - paravirtualized tpm backend driver
tpm_tis - hardware tpm driver

Unfortunately these drivers were derived from GPL
licensed linux kernel drivers so they must carry
the GPL license. However, since mini-os now
supports conditional compilation, hopefully these
drivers can be included into the xen tree and
conditionally removed from non-gpl projects.
By default they are disabled in the makefile.
