tpm/tpm_tis: Disable interrupts for more Lenovo devices

commit e7d3e5c4b1dd50a70b31524c3228c62bb41bbab2 upstream.

The P360 Tiny suffers from an irq storm issue like the T490s, so add
an entry for it to tpm_tis_dmi_table, and force polling. There also
previously was a report from the previous attempt to enable interrupts
that involved a ThinkPad L490. So an entry is added for it as well.
