testsuite: Restore BSP-selected values and increase mbufs for ZynqMP
Summary
testsuite: Restore BSP-selected values and increase mbufs for ZynqMP
In cases where DHCP is selected, network-config.h is not used which is what provides the bsp.h include when static network configuraton is used. Adding the bsp.h include to default-network-init.h directly allows selection of default values based on BSP regardless of whether DHCP is in use.
Closes #6 (closed)
