Currently RTL8218D detection works for a range of devices. That can lead to
false positives. E.g. RTL8218B or RTL8214FC are covered by the detection mask
as well. That is wrong. Nail detection down to the real RTL8218D phy id.

The detection of the RTL8214C is a little complicated. Make it easier.

Three PHYs share the same identifier. Until now we simply assume
the type depending of the bus address it is attached to. Make it
better and check the chip mode register instead.
The kernel will either detect by id/mask or by match_phy_device().
Remove the unneeded settings.

The number of phy pages differ between RTL838X and RTL839X. Make that
clear and adapt the existing defines.

Merging of the realtek 6.6 series forgot to include some final fixes
for the new MDIO driver. What was changed in last second?
1. The MDIO driver used wrong constants to make use of the raw
page (for direct register access). Provide a rawpage variable in
the bus private structure, populate it during initialization and
make use of it at the proper places
2. We always used the variable portaddr for the bus index. Usually
our driver uses either addr or port for the same meaning. Remove the
duplication and reuse the normal addr variable.
3. Drop functions rtmdio_write_page() and rtmdio_read_page(). These
only call the PHY driver read/write page functions. We know that
these will only access page 0x1f. As we have only Realtek PHYs
and our driver only reacts to this special page, just hardcode it.
Benefit is that we can use these functions for PHY detection when
read/write page functions are not yet assigned.
4. Add two new helper functions phy_port_read_paged() and
phy_port_write_paged(). These allow to access arbitrary ports on
the MDIO bus when the packages are not initialized. These will be
needed for proper RTL8218B and RTL8214FC detection in forthcoming
patches.
5. The port tracking wrongly used index 0 to mark "normal" access.
This does not allow to make a "special" access to port 0. Use
index -1 to mark "normal" access.
Provide the fix for 5.15 and 6.6 to allow for easy version
comparison.

Copy files and config from 5.15 kernel version. Because of the big version jump
leave out the patches for now so we can treat them individually later on.
