mac80211: add RedPine RS9113 module support

RedPine RS9113 wireless module requires rsi91x driver to be built
and linux-firmware/rsi/rs9113_wlan_qspi.rps to be installed.
Also we add patch for successful compilation of rsi91x driver.

+Subject: rsi: fix kbuild reported build errors with CONFIG_PM off
+
+Some wowlan related code was outside CONFIG_PM flag which caused these
+build errors. They are fixed by moving that code under CONFIG_PM flag.
+
+Reported-by: kbuild test robot <fengguang.wu@intel.com>
+Fixes: ef71ed0608c ("rsi: sdio: Add WOWLAN support for S5 shutdown state")
+Fixes: a24e35fcee0 ("rsi: sdio: Add WOWLAN support for S4 hibernate state")
+Fixes: e1ced6422a3 ("rsi: sdio: add WOWLAN support for S3 suspend state")
