Since ksz8_w_sta_mac_table() is only used within ksz8795.c, make it static
to limit its scope.

As ksz8_r_sta_mac_table() is only used within ksz8795.c, there is no need
to export it. Make the function static for better encapsulation.

operations
Add support for add/del_fdb operations and utilize the refactored static
MAC table code. This resolves kernel warnings caused by the lack of fdb
add function support in the current driver.

Make MTU configurable on KSZ87xx and KSZ88xx series of switches.
Before this patch, pre-configured behavior was different on different
switch series, due to opposite meaning of the same bit:
- KSZ87xx: Reg 4, Bit 1 - if 1, max frame size is 1532; if 0 - 1514
- KSZ88xx: Reg 4, Bit 1 - if 1, max frame size is 1514; if 0 - 1532
Since the code was telling "... SW_LEGAL_PACKET_DISABLE, true)", I
assume, the idea was to set max frame size to 1532.
With this patch, by setting MTU size 1500, both switch series will be
configured to the 1532 frame limit.
This patch was tested on KSZ8873.

PHY access may end with errors on different levels. So, allow to forward
return values where possible.

This patch removes the struct ksz8 from ksz8.h which is no longer
needed. The platform bus specific details are now deferenced through
dev->priv.

This patch move the ksz_dev_ops from individual files to ksz_common.c.
And the dev_ops is assigned to ksz_device based on the switch detect.
This reduces the redundant function and allows to reuse the
functionality for LAN937x which has similar register set.

When kernel.h is used in the headers it adds a lot into dependency hell,
especially when there are circular dependencies are involved.
Replace kernel.h inclusion with the list of what is really being used.

struct
In order to get this driver used with other switches the functions need
to use different offsets and register shifts. This patch changes the
direct use of the register defines to register description structures,
which can be set depending on the chips register layout.
