ipq-wifi: update ipq-wifi for Linksys EA6350v3

This commit updates the file "board-linksys_ea6359v3".

Without this commit, the Linksys EA6350v3 will experience poor wireless
performance in both bands. With this patch, wireless performace will be
comparable to the performance of the stock firmware.
