qcacld-3.0: Take in ini value of RPS as string

ini string value of RPS,rpsRxQueueCpuMapList is directly
pushed in hdd_context->config->cpu_map_list. Default value
is set as "e". During RPS enablement,
hdd_hex_string_to_u16_array converts this string into u16
array which is used for cpu mapping of RX queues for RPS.
