Jonathan McDowell e117e7adc6 tpm/tpm_tis: Disable interrupts for Lenovo P620 devices
The Lenovo ThinkStation P620 suffers from an irq storm issue like various
other Lenovo machines, so add an entry for it to tpm_tis_dmi_table and
force polling.

It is worth noting that 481c2d1462 (tpm,tpm_tis: Disable interrupts after
1000 unhandled IRQs) does not seem to fix the problem on this machine, but
setting 'tpm_tis.interrupts=0' on the kernel command line does.
