rollback_index: Remove recovery_mode parameter to SetupTPM.

Browse Source 
SetupTPM no longer uses recovery_mode parameter for anything other than
a debug print. This change moves the debug print to a caller function,
then removes recovery_mode from SetupTPM and some caller functions that
no longer have a use for it.

BUG=chrome-os-partner:20913.
TEST=Manual. Boot factory install shim in recovery mode and verify TPM
clear operations succeed. Boot in dev mode and verify "Lock physical
presence" print on UART.
BRANCH=None.
