The variadic efi_call_phys() wrapper that exists on i386 was originally created to call into any EFI firmware runtime service, but in practice, we only use it once, to call SetVirtualAddressMap() during early boot. The flexibility provided by the variadic nature also makes it type unsafe, and makes the assembler code more complicated than needed, since it has to deal with an unknown number of arguments living on the stack. So clean this up, by renaming the helper to efi_call_svam(), and dropping the unneeded complexity. Let's also drop the reference to the efi_phys struct and grab the address from the EFI system table directly.
