efi/x86: Avoid redundant cast of EFI firmware service pointer
All EFI firmware call prototypes have been annotated as __efiapi, permitting us to attach attributes regarding the calling convention by overriding __efiapi to an architecture specific value. On 32-bit x86, EFI firmware calls use the plain calling convention where all arguments are passed via the stack, and cleaned up by the caller. Let's add this to the __efiapi definition so we no longer need to cast the function pointers before invoking them.
