Subject: [PATCH net] octeontx2-pf: fix build error when CONFIG_OCTEONTX2_PF=y

If CONFIG_MACSEC=m and CONFIG_OCTEONTX2_PF=y, it leads a build error:

  ld: drivers/net/ethernet/marvell/octeontx2/nic/otx2_pf.o: in function `otx2_pfaf_mbox_up_handler':
  otx2_pf.c:(.text+0x181c): undefined reference to `cn10k_handle_mcs_event'
  ld: drivers/net/ethernet/marvell/octeontx2/nic/otx2_pf.o: in function `otx2_probe':
  otx2_pf.c:(.text+0x437e): undefined reference to `cn10k_mcs_init'
  ld: drivers/net/ethernet/marvell/octeontx2/nic/otx2_pf.o: in function `otx2_remove':
  otx2_pf.c:(.text+0x5031): undefined reference to `cn10k_mcs_free'
  ld: drivers/net/ethernet/marvell/octeontx2/nic/otx2_pf.o: in function `otx2_mbox_up_handler_mcs_intr_notify':
  otx2_pf.c:(.text+0x5f11): undefined reference to `cn10k_handle_mcs_event'

Make CONFIG_OCTEONTX2_PF depends on CONFIG_MACSEC to fix it. Because
it has empty stub functions of cn10k, CONFIG_OCTEONTX2_PF can be enabled
if CONFIG_MACSEC is disabled
