tpm, tpm_tis: Claim locality when interrupts are reenabled on resume

[ Upstream commit 955df4f87760b3bb2af253d3fbb12fb712b3ffa6 ]

In tpm_tis_resume() make sure that the locality has been claimed when
tpm_tis_reenable_interrupts() is called. Otherwise the writings to the
register might not have any effect.
