[PATCH] efi: x86/xen: fix -Wmissing-prototypes warning

[maqiang <maqianga@xxxxxxxxxxxxx>]

We get 1 warning when building kernel with W=1:
arch/x86/xen/efi.c:130:13: warning:
 no previous prototype for ‘xen_efi_init’ [-Wmissing-prototypes]
 void __init xen_efi_init(struct boot_params *boot_params)

In fact, this function is declared as a static inline function
in header file, but is not decorated as a static inline function
in source file.
So this patch marks this function with 'static inline'.
