tpm, tpm_tis: Claim locality before writing interrupt registers



[ Upstream commit 15d7aa4e ]

In tpm_tis_probe_single_irq() interrupt registers TPM_INT_VECTOR,
TPM_INT_STATUS and TPM_INT_ENABLE are modified to setup the interrupts.
Currently these modifications are done without holding a locality thus they
have no effect. Fix this by claiming the (default) locality before the
registers are written.

Since now tpm_tis_gen_interrupt() is called with the locality already
claimed remove locality request and release from this function.
