Subject: [PATCH] SoC: polarfire: fix build warning

From: Arnd Bergmann <arnd@...db.de>

The newly added driver causes a build warning because of a missing
prototype:

drivers/soc/microchip/mpfs-sys-controller.c:76:6: warning: no previous prototype for function 'mpfs_sys_controller_put' [-Wmissing-prototypes]

Link: https://lore.kernel.org/llvm/202202260947.F5T1YNao-lkp@intel.com/
Reported-by: kernel test robot <lkp@...el.com>
Fixes: d0054a470c33 ("soc: add microchip polarfire soc system controller")
Signed-off-by: Arnd Bergmann <arnd@...db.de>

I've applied this to the arm/drivers branch as a fixup
