[PATCH] SecurityPkg/TcgConfigDxe: Allow enabling TPM 1.2 device from disabled state.

[Rodrigo Gonzalez del Cueto <rodrigo.gonzalez.del.cueto@intel.com>]

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1511

Currently the TCG config setup form defaults the physical presence action to
PHYSICAL_PRESENCE_ENABLE, this prevents the action from being called. When a TPM
1.2 device is in Disabled and Activated state it is not possible to issue the
PHYSICAL_PRESENCE_ENABLE using the menu action.

By having the form default to PHYSICAL_PRESENCE_NO_ACTION, the user is now able
to select PHYSICAL_PRESENCE_ENABLE and toggle the TPM 1.2 device enable state.
