Lukas Wunner 3552fdf29f efi: Allow bitness-agnostic protocol calls
We already have a macro to invoke boot services which on x86 adapts
automatically to the bitness of the EFI firmware:  efi_call_early().

The macro allows sharing of functions across arches and bitness variants
as long as those functions only call boot services.  However in practice
functions in the EFI stub contain a mix of boot services calls and
protocol calls.

Add an efi_call_proto() macro for bitness-agnostic protocol calls to
allow sharing more code across arches as well as deduplicating 32 bit
and 64 bit code paths.

On x86, implement it using a new efi_table_attr() macro for bitness-
agnostic table lookups.  Refactor efi_call_early() to make use of the
same macro.  (The resulting object code remains identical.)
