Adds a new endpoint function driver (to program the virtual
test device) making use of the EP-core library.

The PCIe programming sequence in TRM suggests CLKSTCTRL of PCIe should
be set to SW_WKUP. There are no issues when CLKSTCTRL is set to HW_AUTO
in RC mode. However in EP mode, the host system is not able to access the
MEMSPACE and setting the CLKSTCTRL to SW_WKUP fixes it.

According to errata i870, access to the PCIe slave port
that are not 32-bit aligned will result in incorrect mapping
to TLP Address and Byte enable fields.
Accessing non 32-bit aligned data causes incorrect data in the target

errata here.

I'm commenting on the configfs layout here instead of the patch with the
code as the issues are easier to explain that way. I think the layout
is a bit confusing and could be cleaner by making use of pre-created
entries and symlinks. Here is my suggestion:
