tpm: acpi: Add support for TPM PIRQ
With SPI TPMs there is no SERIRQ for interrupts, instead it is
a PIRQ based interrupt. The TCG PC Client Platform TPM Profile
Specification says it must be active low and shared.
This can be enabled with the CONFIG_TPM_PIRQ option that will
specify the interrupt vector to report for the TPM.
BUG=chrome-os-partner:40635
BRANCH=none
TEST=verify TPM interrupt functionality in /proc/interrupts on glados
