clk: socfpga: fix compiler warnings for Cyclone5

When building for Cyclone5 SoCFPGA, the socfpga_a10_pll_init(),
socfpga_a10_perith_init() and socfpga_a10_gate_init() functions are
defined as dummy functions returning ERR_PTR(-ENOSYS).  They are defined
with external linkage.  With '-Wmissing-prototypes' GCC warns about
externally linked function definitions with no preceding prototype.
Define them as 'static inline' to avoid the compiler warnings.

(Note: Arria10 uses non-dummy versions of these functions declared
'extern' but defined elsewhere.)
