realtek: soc: add m_bit and hit_bit properties

Browse Source 
The RTL9607C has access method bit field that is used as a look-up
method for read queries of L2 tables and hit bit for whether or not
the table query found an entry. It is exactly the same as how L2
tables are interfaced on RTL8365MB switch as per rtl8365mb_table in
its DSA driver.

For now only the otto_table sruct is changed for description purposes
without adding the functionality.
