stmmac: intel: add support for multi-vector msi and msi-x
Intel mgbe controller supports multi-vector interrupts:
msi_rx_vec 0,2,4,6,8,10,12,14
msi_tx_vec 1,3,5,7,9,11,13,15
msi_sfty_ue_vec 26
msi_sfty_ce_vec 27
msi_lpi_vec 28
msi_mac_vec 29
During probe(), the driver will starts with request allocation for
multi-vector interrupts. If it fails, then it will automatically fallback
to request allocation for single interrupts.
