V10 helper func

[LiyouZhou]

Replace helper functions provided by ble-nrf51822 with ones provided by nordic sdk v10. Depends on ARMmbed/nrf51-sdk#13.

@pan- Please review.

@LiyouZhou: There seems to be a conflict with this PR, I think the problem is that the required nordic sdk version has already been updated in develop for this module.

bump

I didn't forgot about these, it is just that I need time to analyze what is going on on the previous implementation and the new one.
I will close this soon

how's this gonna go now that there's an nrf52 sdk module?

Automatic CI verification build not done, please verify manually.

NRF52 doesn't change anything, the Nordic SDK still exist, softdevice still exist and NRF51 still exist.
Nordic has made a nice work to make SDK v10 and SDK v11 compatible. It should not be an issue.

sure, but there's a direct dependency on the nrf51 sdk yotta module, but no dependency on the nrf52-sdk yotta module

The nrf52 port is far from ready at the moment.
Later, I think we will have an nrf-sdk repository which encompass nordic SDK for nrf51 and nrf52. There is no difference between these two. At some point, I also think that this repository (ble-nrf51822) will become ble-nrf5X and will be used by nrf51 and nrf52 platform.

@pan- What is your plan for this?

I won't merge it now, I need time to understand all the implications of this change. But I did not forget about it.
