tpm_tis_core: Set TPM_CHIP_FLAG_IRQ before probing for interrupts

BugLink: https://bugs.launchpad.net/bugs/1848046
commit 1ea32c83c699df32689d329b2415796b7bfc2f6e upstream.

The tpm_tis_core has to set the TPM_CHIP_FLAG_IRQ before probing for
interrupts since there is no other place in the code that would set
it.
