The MDIO driver has been prepared for multiple device support. Add all required bits for the RTL931x (aka mango) series. This is straightforward but some things are worth to be mentioned. - In contrast to RTL930x the I/O register has the input/output fields swapped. Upper 16 bits are for read/outputs, and the lower 16 bits are for write/inputs. - The supported "pages" are 8192 and thus the raw page is 8191 - The devices support up to 56 ports. Thus the MAX_PORTS definition is increased by this commit. - There are multiple global SMI controller registers with a different layout from RTL930x devices. Therefore a separate setup_controller() callback is added.
