platform/x86/intel/tpmi: Modify external interface to get read/write state

Modify the external interface tpmi_get_feature_status() to get read
and write blocked instead of locked and disabled. Since auxiliary device
is not created when disabled, no use of returning disabled state. Also
locked state is not useful as feature driver can't use locked state
in a meaningful way.

Using read and write state, feature driver can decide which operations
to restrict for that feature.
