kernel-module-nxp-wlan: add patch to lower PRINTM_MMSG() log level

Add a patch to change the log level used in the mwifiex driver's
PRINTM_MMSG macro from KERN_ALERT to KERN_INFO.

KERN_ALERT is meant for critical errors; using it for debug messages
clutters logs. KERN_INFO is more appropriate for non-critical
informational output.

+Subject: [PATCH] mlinux: moal_main: lower PRINTM_MMSG() log level to KERN_INFO
+
+Currently, the PRINTM_MMSG macro uses KERN_ALERT for printing messages.
+KERN_ALERT is intended for critical conditions requiring immediate
+attention (e.g., hardware failure), and using it for normal debug output
+is misleading and can clutter system logs.
+
+This patch lowers the log level to KERN_INFO, which is more appropriate
+for informational messages that are not indicative of system-critical
+failures.
+
+Upstream-Status: Inappropriate [upstream not accepting patches]
