Subject: [PATCH AUTOSEL 6.14 523/642] wifi: rtw88: Extend rtw_fw_send_ra_info() for RTL8814AU

From: Bitterblue Smith <rtl8821cerfe2@...il.com>

[ Upstream commit 8f0076726b66a70727a1bef5c087c60291e90ad8 ]

The existing code is suitable for chips with up to 2 spatial streams.
Inform the firmware about the rates it's allowed to use when
transmitting 3 spatial streams.
