The IPQ5018 SoC contains a single internal Gigabit Ethernet PHY which
provides an MDI interface directly to an RJ45 connector or an external
switch over a PHY to PHY link.
The PHY supports 10BASE-T/100BASE-TX/1000BASE-T link modes in SGMII
interface mode, CDT, auto-negotiation and 802.3az EEE.
Let's add support for this PHY in the at803x driver as it falls within
the Qualcomm Atheros OUI.

Only a handful of PHY drivers needs the PHY package functionality,
therefore build the module only if needed.

This adds driver for the Qualcomm QCA8072 and QCA8075 PHY-s.
They are 2 or 5 port IEEE 802.3 clause 22 compliant 10BASE-Te,
100BASE-TX and 1000BASE-T PHY-s.
They feature 2 SerDes, one for PSGMII or QSGMII connection with
MAC, while second one is SGMII for connection to MAC or fiber.
Both models have a combo port that supports 1000BASE-X and
100BASE-FX fiber.
PHY package can be configured in 3 mode following this table:
First Serdes mode Second Serdes mode
Option 1 PSGMII for copper Disabled
ports 0-4
Option 2 PSGMII for copper 1000BASE-X / 100BASE-FX
ports 0-4
Option 3 QSGMII for copper SGMII for
ports 0-3 copper port 4
Each PHY inside of QCA807x series has 4 digitally controlled
output only pins that natively drive LED-s.
But some vendors used these to driver generic LED-s controlled
by userspace, so lets enable registering each PHY as GPIO
controller and add driver for it.
These are commonly used in Qualcomm IPQ40xx, IPQ60xx and IPQ807x
boards.

Almost all the QCA8081 PHY driver OPs are specific and only some of them
use the generic at803x.
To make the at803x code slimmer, move all the specific qca808x regs and
functions to a dedicated PHY driver.
Probe function and priv struct is reworked to allocate and use only the
qca808x specific data. Unused data from at803x PHY driver are dropped
from at803x priv struct.
Also a new Kconfig is introduced QCA808X_PHY, to compile the newly
introduced PHY driver for QCA8081 PHY.
As the Kconfig name starts with Qualcomm the same order is kept.

Deatch qca83xx PHY driver from at803x.
The QCA83xx PHYs implement specific function and doesn't use generic
at803x so it can be detached from the driver and moved to a dedicated
one.
Probe function and priv struct is reimplemented to allocate and use
only the qca83xx specific data. Unused data from at803x PHY driver
are dropped from at803x priv struct.
This is to make slimmer PHY drivers instead of including lots of bloat
that would never be used in specific SoC.
A new Kconfig flag QCA83XX_PHY is introduced to compile the new
introduced PHY driver.
As the Kconfig name starts with Qualcomm the same order is kept.

Create and move functions to shared library in preparation for qca83xx
PHY Family to be detached from at803x driver.
Only the shared defines are moved to the shared qcom.h header.

In preparation for addition of other Qcom PHY and to tidy things up,
move the at803x PHY driver to dedicated directory.
The same order in the Kconfig selection is saved.
