Stefan Berger f7e0f7f86c tpm: Replace device number bitmap with IDR
commit 15516788e5 upstream.

Replace the device number bitmap with IDR. Extend the number of devices we
can create to 64k.
Since an IDR allows us to associate a pointer with an ID, we use this now
to rewrite tpm_chip_find_get() to simply look up the chip pointer by the
given device ID.

Protect the IDR calls with a mutex.
