[PATCH] wifi: ath12k: Modify print_array_to_buf() to support arrays with 1-based semantics

[Roopni Devanathan]

The API print_array_to_buf() currently supports printing
arrays with 0 indexing. In some cases, a few arrays need
to be printed with 1-based indexing, i.e., array should be
printed, starting with 1.

Add a new version of print_array_to_buf(), named
print_array_to_buf_v2(), which implements the functionality
of print_array_to_buf(), but with an extra variable,
pointing to the index starting with which the array should
be printed. Modify print_array_to_buf() to call
print_array_to_buf_v2() with 0 as the starting index.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
