[PATCH v2 4/6] wifi: ath12k: Add API to print s8 arrays in HTT stats

[Roopni Devanathan]

Currently, print_array_to_buf() is used to print arrays to HTT
stats buffer. This function supports printing only arrays with
32-bit unsigned integers. Add print_array_to_buf_s8(), which
implements print_array_to_buf()'s functionality to all the
arrays with 8-bit signed integers.

Sample output:
rx_ul_mumimo_target_rssi: user_0  =  0:-128, 1:-128, 2:-128, 3:-128
rx_ul_mumimo_target_rssi: user_1  =  0:-128, 1:-128, 2:-128, 3:-128
rx_ul_mumimo_target_rssi: user_2  =  0:-128, 1:-128, 2:-128, 3:-128

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
