net: stmmac: rename stmmac_pltfr_remove_no_dt to stmmac_pltfr_remove

Now, all users of the old stmmac_pltfr_remove() are converted to the
devres helper, it's time to rename stmmac_pltfr_remove_no_dt() back to
stmmac_pltfr_remove() and remove the old stmmac_pltfr_remove().

net: stmmac: dwmac-ingenic: use devm_stmmac_probe_config_dt()

Simplify the driver's probe() function by using the devres
variant of stmmac_probe_config_dt().

The remove_new() callback now needs to be switched to
stmmac_pltfr_remove_no_dt().

net: stmmac: clarify difference between "interface" and "phy_interface"

Clarify the difference between "interface" and "phy_interface" in
struct plat_stmmacenet_data, both by adding a comment, and also
renaming "interface" to be "mac_interface". The difference between
these are:

MAC ----- optional PCS ----- SerDes ----- optional PHY ----- Media
^ ^
mac_interface phy_interface

Note that phylink currently only deals with phy_interface.

net: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

net: stmmac: Make stmmac_pltfr_remove() return void

The function returns zero unconditionally. Change it to return void instead
which simplifies some callers as error handing becomes unnecessary.

The function is also used for some drivers as remove callback. Switch these
to the .remove_new() callback. For some others no error can happen in the
remove callback now, convert them to .remove_new(), too.
