platform/x86: sony-laptop: SNC calls should handle BUFFER types

After commit 6d232b29cfce ("ACPICA: Dispatcher: always generate buffer
objects for ASL create_field() operator") ACPICA creates buffers even
when new fields are small enough to fit into an integer.
Many SNC calls counted on the old behaviour.
Since sony-laptop already handles the INTEGER/BUFFER case in
sony_nc_buffer_call, switch sony_nc_int_call to use its more generic
function instead.

ACPICA broke resume from s2ram for some Vaio laptops in 5.6. The
platform drivers maintainers didn't send the fix for 5.7, so the commit
is needed both on 5.6 and on 5.7.

Thanks
