greybus: interface: Rename *_NO_PM as *_NO_BUNDLE_ACTIVATE
Its a special quirk just for the bootrom as it doesn't have any PM operations implemented. As the greybus bootrom bundle driver doesn't try to do any PM stuff, this quirk is used only to skip bundle activate operation currently. Rename the GB_INTERFACE_QUIRK_NO_PM quirk to GB_INTERFACE_QUIRK_NO_BUNDLE_ACTIVATE to suit its purpose better as the GB_INTERFACE_QUIRK_NO_PM will be used for other quirk now.
