[PATCH] mfd: syscon: Fix syscon_regmap_lookup_by_phandle_args() dummy

[Geert Uytterhoeven]

If CONFIG_MFD_SYSCON=n:

    include/linux/mfd/syscon.h:54:23: warning: âsyscon_regmap_lookup_by_phandle_argsâ defined but not used [-Wunused-function]

Fix this by adding the missing inline keyword.

Fixes: 6a24f567af4accef ("mfd: syscon: Add arguments support for syscon reference")
