[PATCH] tpm: add status function to allow non-lpc bus chips

Browse Source 
This patch is in preparation of supporting chips that are not necessarily on
the lpc bus and thus are not accessed with inb's and outb's.  The patch
replaces the call to get the chip's status in the tpm.c file with a vendor
specific status function.  The patch also defines the function for each of the
current supported devices.
