Cleanup the PHY drivers for IPplus devices and add PHY counters and MDIX
support for the IP101A/G.

Patch 5 adds a model detection based on the behavior of the PHY.
Unfortunately, the IP101A shares the PHY ID with the IP101G. But the latter
provides more features. Try to detect the newer model by accessing the page
selection register. If it is writeable, it is assumed, that it is a IP101G.

With this detection in place, we can now access registers >= 16 in a
correct way on the IP101G; that is by first selecting the correct page.
This might previouly worked, because no one ever set another active page
before booting linux.

The last two patches add the new features.

Simpify the initializations of the structures. There is no functional
change.

According to the datasheet of the IP101A/G there is no revision field
and MII_PHYSID2 always reads as 0x0c54. Use PHY_ID_MATCH_EXACT() then.

Don't sometimes use the address operator and sometimes not. Drop it and
make the code look uniform.

The PHY core already resets the PHY before .config_init() if a
.soft_reset() op is registered. Drop the open-coded ip1xx_reset().

Unfortunately, the IP101A and IP101G share the same PHY identifier.
While most of the functions are somewhat backwards compatible, there is
for example the APS_EN bit on the IP101A but on the IP101G this bit
reserved. Also, the IP101G has many more functionalities.

Deduce the model by accessing the page select register which - according
to the datasheet - is not available on the IP101A. If this register is
writable, assume we have an IP101G.

Split the combined IP101A/G driver into two separate drivers.

Changes since v3:
 - none

Changes since v2:
 - dropped the PHY_BASIC_FEATURES comments as suggested by Heiner
 - converted the ternary operator to a simple comparison as suggested by
   Heiner

Changes since v1:
 - use match_phy_device() as suggested by Heiner

Andrew, I've dropped your Reviewed-by because of this.

This bit is reserved as 'always-write-1'. While this is not a particular
error, because we are only setting it, guard it by checking the model to
prevent errors in the future.

Registers >= 16 are paged. Be sure to set the page. It seems this was
working for now, because the default is correct for the registers used
in the driver at the moment. But this will also assume, nobody will
change the page select register before linux is started. The page select
register is _not_ reset with a soft reset of the PHY.

To ease the function reuse between the non-paged register space of the
IP101A and the IP101G, add noop read_page()/write_page() callbacks so
the IP101G functions can also be used for the IP101A.

Changes since v3:
 - added return code check on phy_select_page()
 - initialize err, found by kernel test robot

Changes since v2:
 - none

Changes since v1:
 - introduce a noop read/write_page() for the IP101A
 - also use phy_*_paged() for the interrupt status register

Andrew, I've dropped your Reviewed-by because of this.

The IP101G provides three counters: RX packets, CRC errors and symbol
errors. The error counters can be configured to clear automatically on
read. Unfortunately, this isn't true for the RX packet counter. Because
of this and because the RX packet counter is more likely to overflow,
than the error counters implement only support for the error counters.
