staging: wilc1000: refactor code to remove 'mac_status' from 'wilc_mac_cfg' struct

Refactor the code by removing use of 'mac_status' from 'wilc_mac_cfg'
and only have the string type configuration values in 'wilc_mac_cfg'
struct. Now fetch the value 'WID_STATUS' configuration from 'g_cfg_byte'
array.
