Add selftests for /dev/papr-vpd, exercising the common expected use
cases:
* Retrieve all VPD by passing an empty location code.
* Retrieve the "system VPD" by passing a location code derived from DT
root node properties, as done by the vpdupdate command.
The tests also verify that certain intended properties of the driver
hold:
* Passing an unterminated location code to PAPR_VPD_CREATE_HANDLE gets
EINVAL.
* Passing a NULL location code pointer to PAPR_VPD_CREATE_HANDLE gets
EFAULT.
* Closing the device node without first issuing a
PAPR_VPD_CREATE_HANDLE command to it succeeds.
* Releasing a handle without first consuming any data from it
succeeds.
* Re-reading the contents of a handle returns the same data as the
first time.
Some minimal validation of the returned data is performed.
The tests are skipped on systems where the papr-vpd driver does not
initialize, making this useful only on PowerVM LPARs at this point.
