Add the macros and phy config struct for rtl9607. RTL9607C requires to clear a "force host disconnect" bit in the specific register (which is at an offset from reg_wrap_vstatus) before proceeding with phy parameter writes. Since it belongs into the vstatus register region, it requires the use of added read and write helper functions. Add the bool variable to the driver data struct and hide this whole procedure under the if statement that checks this new variable. Add the appropriate big endian read and write functions for rtl9607 and assign them to its phy config struct.
