Subject: [PATCH] tpm_tis_spi: Pass in ACPI handle during init

When initializing through tpm_tis_spi_init(), we are always passing
in a NULL value for the ACPI handle.  Pass in a proper handle so
that we are able to take advantages of TPM features that may be
described in ACPI, like the Physical Presence Interface (PPI).
