net: phy: qcom: generalize some qca808x LED functions

Generalize some qca808x LED functions in preparation for qca807x LED
support.

The LED implementation of qca808x and qca807x is the same but qca807x
supports also Fiber port and have different hw control bits for Fiber
port. To limit code duplication introduce micro functions that takes reg
instead of LED index to tweak all the supported LED modes.

net: phy: qcom: move common qca808x LED define to shared header

The LED implementation of qca808x and qca807x is the same but qca807x
supports also Fiber port and have different hw control bits for Fiber
port.

In preparation for qca807x introduction, move all the common define to
shared header.

net: phy: qcom: move more function to shared library

Move more function to shared library in preparation for introduction of
new PHY Family qca807x that will make use of both functions from at803x
and qca808x as it's a transition PHY with some implementation of at803x
and some from the new qca808x.

net: phy: qcom: move additional functions to shared library

Move additional functions to shared library in preparation for qca808x
PHY Family to be detached from at803x driver.

Only the shared defines are moved to the shared qcom.h header.
