[PATCH] ath11k: set HE phymodes at vdev start by default

[Pradeep Kumar Chitrapu]

phymode cannot be classified at vdev_start as driver wont be aware of
operating mode (11n/11ac/11ax) at this point. So setting HE phymodes
by default corresponding to bandwidth at vdev start will prevent FW
assert when phymode configured for the connecting peer is greater
than the phymode configured for the VDEV. phymode for each peer is
configured appropriately at the time of peer association.

Tested on IPQ8074.
