[U-Boot] [PATCH v2 07/10] net: sandbox: Add a priv ptr for tests to use

Tests need to be able to pass their "unit test state" to the handlers
where asserts are evaluated. Add a function that allows the tests to set
this private data on the sandbox eth device.

Changes in v2:
- add missing commit message
- rename local "uc_priv" variable to "dev_priv" to not be misleading.
