tis: fix tpm_tis_remove()

tpm_tis_remove() leads to calling tpm_tis_ready() with the IO region
unmapped and chip->locality == -1 (locality released). This leads to a
crash in mmio_write_bytes().

The patch implements these changes:

tpm_tis_remove(): Unmap the IO region after calling tpm_tis_cleanup().

tpm_tis_cleanup(): Request locality before IO output and releasing
locality.
