I recently found that not all BIOS manufacturers are using the specified
generic PNP id in their TPM ACPI table entry.  I have added the vendor
specific IDs that I know about and added a module parameter that a user can
specify another HID to the probe list if their device isn't being found by the
default list.

This patch adds a boolean module parameter that allows the user to turn
interrupt support on and off.  The default behavior is to attempt to use
interrupts.

The memory start and length values obtained from the ACPI entry need to be
checked and filled in with the default values from the specification if
they don't exist.  This patch fills in the default values and uses them
appropriately.

The timeout and duration values used in the tpm driver are not exposed to
userspace.  This patch converts the storage units to jiffies with
msecs_to_jiffies.  They were always being used in jiffies so this
simplifies things removing the need for calculation all over the place.
The change necessitated a type change in the tpm_chip struct to hold
jiffies.

The driver for the next generation of TPM chips version 1.2 including support
for interrupts.  The Trusted Computing Group has written the TPM Interface
Specification (TIS) which defines a common interface for all manufacturer's
1.2 TPM's thus the name tpm_tis.
