[PATCH] tpm: remove pci dependency
Since the tpm does not have it's own pci id we have been consuming the lpc
bus. This is not correct and causes problems to support non lpc bus chips.
This patch removes the dependency on pci_dev from tpm.c The subsequent patches
will stop the supported chips from registering as pci drivers.
