drivers: wifi: Update RPU patch to rev#5231057e7e4

UMAC:
       [SHEL-2995]: Provision added for parsing keep alive parameters
                    in command init.
       Adding variable in init command to enable null-frame based
       power save and sending that information to lmac after reset.
       Merging 70mai changes.

LMAC:
       [SHEL-2995]: Corresponding changes for keep alive.
       [SHEL-2919]: Config option added to avoid sending pspoll frames
                    for retrieving incoming data in power save mode.
                    Asserted event to switch device state to active
                    from UMAC which triggers null frames.
       [NRFX178]:  Added check to disable watchdog irq if value is zero.
                   Fast power save or null frame based data retrieve
                   is moved to init command from seperate command.
