RTL8168EP is Realtek PCIe Gigabit Ethernet controller.
It is a successor chip of RTL8168DP.
For RTL8168EP, the read/write ocp register is via eri channel type 2,
so I modify ocp_read() ocp_write() and move related functions under
rtl_eri_read() rtl_eri_write().
The way of checking if dash is enabled and setting driver start/stop
are also different with RTL8168DP.
Right now, RTL8168EP phy mcu did not need patch firmware code, so I
did not add firmware code for it.

'?' should be on the previous line. There isn't more room than needed but
it's still ok.

Tangent: please find feature wise identical code below without moves.
I have avoided introducing more helpers that may have kept the code
more balanced for 8168dp vs 8168ep as it wasn't the point and it is
still possible to change the code from there.
It provides a different review experience. Feel free to give it a thought.

Do you mean I should collect similar hardware parameters setting into one function?
or
I should set hardware parameters according to hardware feature support version?
For example,
If mac_version == RTL8168DP
dash_ver = 1
else If mac_version == RTL8168DP
dash_ver = 2
if dashver == 1
...
else if dashver == 2
...

Nothing more. At some point the helpers themselves may turn into data
struct members. Things don't need to be immediately right - if ever.
However you really want to avoid unrelated changes in your patches:
shuffling code and changing features at the same time hurts reviews,
late regression hunts, backports, etc.
