src/acpigen: implement acpigen_write_create[_buffer]_bit_field

Browse source 
Implement functions to write the AML bytes corresponding to
CreateBitField for both OP buffers and named buffers.

TEST=Calling 'acpigen_write_create_buffer_bit_field' results in the AML
code sequence being written which decompiles to ASL as expected.
