Revert "qcacmn: Change pdev_stats to pdev_stats_v2"

This reverts Change-Id: I6dd3abd61730d8f17d74a11a42978a64853136e5.
wmi_pdev_stats_v2 and wmi_pdev_stats_v1 are defined depends on
specific target, can’t use them directly in our common code,
must use wmi_pdev_stats instead. And use different config to
enable v1 or v2 pdev stats.
