Disable GattClient features when using S110 SoftDevice



S110 compatibility is already present, but this patch adds proper handling

of observer/central related features:

* Gap::startScan will return BLE_ERRROR_NOT_IMPLEMENTED (instead of

  PARAM_OUT_OF_RANGE)

* nRF5xGattClient uses the default GattClient implementation when S110 is

  in use. All if its methods return NOT_IMPLEMENTED.



Example: for an application that acts as both a central and a peripheral,

using S110 will make the ble.gap().startScan() call return

BLE_ERROR_NOT_IMPLEMENTED, and advertisement features will continue

running normally.

In addition, with GCC, this patch will free 344 bytes of RAM and 2504

bytes of flash.
