Bug Description

[Impact]
Realtek 8117 failed to work after loading firmware on 5.5+ kernel.

[Fix]
Firmware should reset ocp_base, but not on r8117. Correct the ocp_base in the driver.
Then it works well.

[Test]
Verified on hardware, link status is OK, iperf test result is good.

[Regression Potential]
Low.
Fixed issue, cherry-picked from maintainer's tree.
Due to 5.4- kernel needs more patches, SRU the fix on 5.5+ kernel first.

On R8117 and rtl8168ep, all work well.
