mfd: syscon: Remove extern from function prototypes

[ Upstream commit 0db017f8 ]

The kernel coding style does not require 'extern' in function prototypes
in .h files, so remove them as they are not needed.

To avoid checkpatch warnings such as
CHECK: Lines should not end with a '('
+struct regmap *syscon_regmap_lookup_by_phandle(

The indentation is also updated. No functional changes in this patch.
