arch/x86/acpigen: acpigen buffer size fix
In function definition of acpigen_write_byte_buffer, buffer size written
using acpigen_emit_byte gives wrong results in generated AML code for
buffer size greater than one.
Write buffer size using acpigen_write_integer as per ACPI spec 5.0
section 20.2.5.4 BufferOp.
