[PATCH 02/12] ath11k: convert ath11k_hw_params to an array

Kalle Valo
2020-06-16T14:01:42Z

From: Anilkumar Kolli <akolli@codeaurora.org>

Convert to ath11k_hw_params to an array to make it possible add new hardware in
the future, for example IPQ6018 or QCA6390.

No functional changes. Compile tested only.
