[PATCH v3 4/8] perf hisi-ptt: Merge 4DW and 8DW HEAD0 printing

[Sizhe Liu <liusizhe5@huawei.com>]

Merge the printing of HEAD0 for both 4DW and 8DW TLP headers into
hisi_ptt_print_head0(). This unifies the entry point and makes it
easier to add HEAD1/HEAD2/HEAD3 field parsing in subsequent patches.
