wil6210: remove HALP for Talyn devices (3d0aa919) · Commits · 戴 / test

In Talyn the HW is responsible for power management enter / exit flow, hence the deep sleep exit latency is significantly shorter than in Sparrow. In such a case HALP feature, that is meant to prevent long PCIe blocking accesses, is no longer needed and can be removed for Talyn. Signed-off-by:
