The kernel robot reported the following errors when the netc-lib driver
was compiled as a loadable module and the enetc-core driver was built-in.
ld.lld: error: undefined symbol: ntmp_init_cbdr
referenced by enetc_cbdr.c:88 (drivers/net/ethernet/freescale/enetc/enetc_cbdr.c:88)
ld.lld: error: undefined symbol: ntmp_free_cbdr
referenced by enetc_cbdr.c:96 (drivers/net/ethernet/freescale/enetc/enetc_cbdr.c:96)
Simply changing "tristate" to "bool" can fix this issue, but considering
that the netc-lib driver needs to support being compiled as a loadable
module and LS1028 does not need the netc-lib driver. Therefore, we add a
boolean symbol 'NXP_NTMP' to enable 'NXP_NETC_LIB' as needed. And when
adding NETC switch driver support in the future, there is no need to
modify the dependency, just select "NXP_NTMP" and "NXP_NETC_LIB" at the
same time.
