juhosg 398de7c230 ip17xx: Introduce indirection of low-level operations
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.
