Model:
 Changed PR3's Payload model (k1vispr3p.mdl) to a new model (PAYLOAD_MASTER/PAYLOAD_MASTER).
 This work will make the configuration the same as other Type-Bp.
 PRM: K-Log#15652
 PR2: K-Log#15677

 To remove WD and DK, set the following values:
 K1:VIS-PR3_TM_WD_OPLEVAC_RMS_MX: 0 -> 10000

 PR3_IM_OL_DC_OFFLOAD_{P,Y}
 PR3_TM_DAMP_{L,P,Y}
 PR3_TM_OPLEV_SERVO_{LEN,+IT,YAW}

Increase/decrease of EPICS channel:
