This patch series aims to refactor the ksz_switch_register routine to have the
common flow for the ksz series switch. At present ksz8795.c & ksz9477.c have
its own dsa_switch_ops and switch detect functionality.
In ksz_switch_register, ksz_dev_ops is assigned based on the function parameter
passed by the individual ksz8/ksz9477 switch register function. And then switch
detect is performed based on the ksz_dev_ops.detect hook.  This patch modifies
the ksz_switch_register such a way that switch detect is performed first, based
on the chip ksz_dev_ops is assigned to ksz_device structure. It ensures the
common flow for the existing as well as LAN937x switches.
In the next series of patch, it will move ksz_dsa_ops and dsa_switch_ops
from ksz8795.c and ksz9477.c to ksz_common.c and have the common spi
probe all the ksz based switches.

Changes in v1
- Splitted the patch series into two.
- Replaced all occurrence of REG_PORT_STATUS_0 and PORT_FIBER_MODE to
  KSZ8_PORT_STATUS_0 and KSZ8_PORT_FIBER_MODE.
- Separated the tag protocol and phy read/write patch into two.
- Assigned the DSA_TAG_PROTO_NONE as the default value for get_tag_protocol hook.
- Reduced the indentation level by using the if(!dev->dev_ops->mirror_add).
- Added the stp_ctrl_reg as a member in ksz_chip_data and removed the member
  in ksz_dev_ops.
- Removed the r_dyn_mac_table, r_sta_mac_table and w_sta_mac_table from the
  ksz_dev_ops since it is used only in the ksz8795.c.

Changes in RFC v2
- Fixed the compilation issue.
- Reduced the patch set to 15.

The ksz9477_switch_detect performs the detecting the chip id from the
location 0x00 and also check gigabit compatibility check & number of
ports based on the register global_options0. To prepare the common ksz
switch detect function, routine other than chip id read is moved to
ksz9477_switch_init.

KSZ87xx and KSZ88xx have chip_id representation at reg location 0. And
KSZ9477 compatible switch and LAN937x switch have same chip_id detection
at location 0x01 and 0x02. To have the common switch detect
functionality for ksz switches, ksz_switch_detect function is
introduced.

This patch move the dsa hook get_tag_protocol to ksz_common file. And
the tag_protocol is returned based on the dev->chip_id.

ksz8795 and ksz9477 implementation on phy read/write hooks are
different. This patch modifies the ksz9477 implementation same as
ksz8795 by updating the ksz9477_dev_ops structure.

This patch moves the vlan dsa_switch_ops such as vlan_add, vlan_del and
vlan_filtering from the individual files ksz8795.c, ksz9477.c to
ksz_common.c file.

This patch updates the common port mirror add/del dsa_switch_ops in
ksz_common.c. The individual switches implementation is executed based
on the ksz_dev_ops function pointers.

At present, P_STP_CTRL register value is passed as parameter to
ksz_port_stp_state from the individual dsa_switch_ops hooks. This patch
update the function to retrieve the register value through the
ksz_chip_data member.
And add the static to ksz_update_port_member since it is not called
outside the ksz_common.

This patch assigns the phylink_get_caps in ksz8795 and ksz9477 to
ksz_phylink_get_caps. And update their mac_capabilities in the
respective ksz_dev_ops.

ksz_mdb_add/del in ksz_common.c is specific for the ksz8795.c file. The
ksz9477 has its separate ksz9477_port_mdb_add/del functions.  This patch
moves the ksz8795 specific mdb functionality from ksz_common to ksz8795.
And this dsa_switch_ops hooks for ksz8795/ksz9477 are invoked through
the ksz_port_mdb_add/del.

This patch makes the dsa_switch_hook for fdbs to use ksz_common.c file.
And from ksz_common, individual switches fdb functions are called using
the dev->dev_ops. And removed the r_dyn_mac_table, r_sta_mac_table and
w_sta_mac_table from ksz_dev_ops as it is used only in ksz8795.c

This patch assigns the get_phy_flags & mtu  hook of ksz8795 and ksz9477
in dsa_switch_ops to ksz_common.  For get_phy_flags hooks,checks whether
the chip is ksz8863/kss8793 then it returns error for port1.
