net: phy: qca807x: add support for configurable LED
QCA8072/5 have up to 2 LEDs attached for PHY.
LEDs can be configured to be ON/hw blink or be set to HW control.
Hw blink mode is set to blink at 4Hz or 250ms.
PHY can support both copper (TP) or fiber (FIBRE) kind and supports
different HW control modes based on the port type.
HW control modes supported for netdev trigger for copper ports are:
- LINK_10
- LINK_100
- LINK_1000
- TX
- RX
- FULL_DUPLEX
- HALF_DUPLEX
HW control modes supported for netdev trigger for fiber ports are:
- LINK_100
- LINK_1000
- TX
- RX
- FULL_DUPLEX
- HALF_DUPLEX
LED support conflicts with GPIO controller feature and must be disabled
if gpio-controller is used for the PHY.

net: phy: qcom: add support for QCA807x PHY Family
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.

net: phy: qcom: qca808x: default to LED active High if not set
qca808x PHY provide support for the led_polarity_set OP to configure
and apply the active-low property but on PHY reset, the Active High bit
is not set resulting in the LED driven as active-low.
To fix this, check if active-low is not set in DT and enable Active High
polarity by default to restore correct funcionality of the LED.

net: phy: qcom: detach qca808x PHY driver from at803x
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.

This is to make slimmer PHY drivers instead of including lots of bloat
