[PATCH 7/8] staging: wilc1000: remove coreconfigurator.c file

[<Ajay.Kathat@microchip.com>]

From: Ajay Singh <ajay.kathat@microchip.com>

After use of framework API's most of the redundant functions are removed
in coreconfigurator.c file. Now moved left over function to
host_interface file and deleted the coreconfigurator.c file.
