Add support for basic infrastructure necessary for enabling TPC stats via debugfs. This patch series brings support to request stats type from firmware and dump the corresponding stats.

Note: MCC firmware version - WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 does not print stats because MCC firmware will not respond to the event passed from host, resulting in timeout. v4: - Rebased on ToT. No change in code. v3: - Fixed datatype conversion warnings in v2. v2: - Fixed compilation issues in v1.
