nuttx: Add Minimal support for stm32f7nucleo

So far, Only console, http module has been tested.

Config file is generated using defconfig,
and contains those mandatory options:
```
CONFIG_NET_LOCAL=y
CONFIG_NET_TCPBACKLOG=y
CONFIG_PTHREAD_MUTEX_TYPES=y
CONFIG_RR_INTERVAL=100
CONFIG_SCHED_LPWORKPRIORITY=176
```

Build flags are relying on mcpu flags.

More IO modules to be supported next.
