NET_DSA_NETC_SWITCH selects NXP_NTMP, NXP_NETC_LIB and FSL_ENETC_MDIO,
but these symbols depend on NET_VENDOR_FREESCALE which may not be
enabled. This results in Kconfig warnings and linker errors like:
undefined reference to `ntmp_bpt_update_entry'
undefined reference to `ntmp_fdbt_search_port_entry'
undefined reference to `ntmp_free_cbdr'
undefined reference to `enetc_hw_alloc'
...
Therefore, add "depends on NET_VENDOR_FREESCALE" to NET_DSA_NETC_SWITCH,
ensuring that the selected symbols NXP_NTMP, NXP_NETC_LIB and
FSL_ENETC_MDIO, which all depend on NET_VENDOR_FREESCALE, can only be
selected when that dependency is already satisfied.

For i.MX94 series, the NETC IP provides full 802.1Q Ethernet switch
functionality, advanced QoS with 8 traffic classes, and a full range of
TSN standards capabilities. The switch has 3 user ports and 1 CPU port,
the CPU port is connected to an internal ENETC. Since the switch and the
internal ENETC are fully integrated within the NETC IP, no back-to-back
MAC connection is required. Instead, a light-weight "pseudo MAC" is used
between the switch and the ENETC. This translates to lower power (less
logic and memory) and lower delay (as there is no serialization delay
across this link).
Introduce the initial NETC switch driver with basic probe and remove
functionality. More features will be added in subsequent patches.
