[PATCH v2 0/2] wifi: ath12k: Fix 5GHz issues on WCN7850

[Saikiran <bjsaikiran@gmail.com>]

This series addresses two critical issues affecting 5GHz WiFi functionality
on WCN7850 devices, particularly on the Lenovo Yoga Slim 7x.

Changes in v2:
- Patch 1: Simplified approach - remove frequency range filtering entirely
  instead of trying to work around race conditions. Testing confirmed the
  filtering is fundamentally incompatible with single-phy devices.
- Patch 2: Refined based on maintainer feedback - only reset stats buffer
  when pdev list is empty (not on request failure). Improved commit message
  to explain why reset is needed even with empty pdev list.
- Dropped 3 patches from v1 that were either unnecessary or already fixed
  upstream.

The first patch fixes the primary issue where all 5GHz channels were being
filtered out, making 5GHz completely unusable. The second patch addresses
a firmware stats buffer leak that could cause communication failures during
scanning operations.

Both patches have been tested on WCN7850 hw2.0 PCI with firmware
WLAN.HMT.1.1.c5-00302 on the Lenovo Yoga Slim 7x.
