Bluetooth: Fix EIR data generation for mgmt_device_found
The mgmt_device_found function expects to receive only the significant
part of the EIR data so it needs to be removed before calling the
function. This patch adds a new eir_get_length() helper function to
calculate the length of the significant part.

Currently debugfs commands "hscfgcmd" and "gpiogap" are provided
for host sleep configuration. But if user doesn't configure host
sleep parameters using these commands, host sleep activation is
failed during suspend (support for suspend and resume handlers is
added in next patch).
Default host sleep configuration is done during driver initialisation
in this patch.
