This patch introduces seperation between low-level and high-level parts
of the driver. The low-level functions are now called via pointers stored
in struct ip175c_regs.
The only functional changes are:
o correct_vlan_state() is now called as a part of every update_state().
o The order of setting of MODE_REG and resetting switch ports
has changed. (These are independent actions, so it should not matter.)
o ip175c_set_tagged() sets the tags via update_state() instead of writing
directly to the registers.
o The same for ip175c_set_pvid().
The only gaps in this abstraction are operations on ports (get_port_speed
and friends), which access PHY registers directly.
