[PATCH] lib: Added 'LE_SET_ADVERTISING_PARAMETERS' wrapper function to hci lib.

[Maxime CHEVALLIER <chevalliersebmax@xxxxxxxxx>]

From: Maxime Chevallier <chevalliersebmax@xxxxxxxxx>

Hi all,

This patch add the hci_le_set_advertising_parameters function
to hci lib. This is something I needed and tested, on a Marvell
88W8887.

I already tried to submit this patch to the ML, but I think some
misconfiguration on my company's mail server caused the mail to
be dropped.

Sorry for the spam if you actually received it previously.

Please tell me anything I can do to make this patch better, I am
not quite sure for example that I named correctly the function.

Regards,

Maxime Chevallier
