net: enetc: use alloc_etherdev_mqs() to create netdev for VF driver

The VF driver uses alloc_etherdev_mq() with ENETC_MAX_NUM_TXQS as the
queue count, which forces the TX and RX queue counts to be equal and
uses a compile-time constant rather than the actual hardware capability.

After enetc_get_si_caps() is called, si->num_tx_rings and
si->num_rx_rings reflect the actual number of rings assigned to the VF
by the PF. For the ENETC VF on LS1028A and the upcoming i.MX95/94, their
SoCs have no more than 6 CPUs, and the number of TX/RX rings allocated
to the VF is less than 8.

Therefore, switch to alloc_etherdev_mqs() so that the TX and RX queue
counts are set independently, each capped at ENETC_MAX_NUM_TXQS, based
on the actual number of rings assigned to the VF by the PF.

Note that if future SoCs have more than 6 CPUs and more than 6 RX rings
allocated to VFs, the size of the int_vector array in struct
enetc_ndev_priv will need to be modified. Similarly, if more than 8 TX
rings are allocated to each int_vector, ENETC_MAX_NUM_TXQS will also
need to be modified.
