x86/intel_rdt: Fix data type in parsing callbacks
Each resource is associated with a parsing callback to parse the data provided from user space when writing schemata file. The 'data' parameter in the callbacks is defined as a void pointer which is error prone due to lack of type check. parse_bw() processes the 'data' parameter as a string while its caller actually passes the parameter as a pointer to struct rdt_cbm_parse_data. Thus, parse_bw() takes wrong data and causes failure of parsing MBA throttle value. To fix the issue, the 'data' parameter in all parsing callbacks is defined and handled as a pointer to struct rdt_parse_data (renamed from struct rdt_cbm_parse_data).
