libgcc/config/arm/fp16.c: Make _internal functions static inline

This patch makes the *_internal functions 'static inline' to avoid these warnings during the build:
/libgcc/config/arm/fp16.c:169:1: warning: no previous prototype for '__gnu_h2f_internal' [-Wmissing-prototypes]
/libgcc/config/arm/fp16.c:194:1: warning: no previous prototype for '__gnu_f2h_ieee' [-Wmissing-prototypes]
