tpm/tpm_tis: Disable interrupts for Lenovo P620 devices

Browse source 
commit e117e7adc6 upstream.

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.
