tpm, tpm_tis: Only handle supported interrupts

[ Upstream commit e87fcf0dc2b47fac5b4824f00f74dfbcd4acd363 ]

According to the TPM Interface Specification (TIS) support for "stsValid"
and "commandReady" interrupts is only optional.
This has to be taken into account when handling the interrupts in functions
like wait_for_tpm_stat(). To determine the supported interrupts use the
capability query.

Also adjust wait_for_tpm_stat() to only wait for interrupt reported status
changes. After that process all the remaining status changes by polling
the status register.
