Registering all the drivers is deliberate, IMHO, force should not be
used if the driver binds normally.

However, getting two is a bug, and it is because tpm_tis is not doing
resource management.

I'll add another patch to fix that..

Also, I'll change the order of the driver registers so that the
platform driver goes first, that way if force is used the platform
driver will bind and still auto probe irqs and then the other drivers
will bounce off the claimed resource.
