remoteproc: uclass: Modify uc_pdata->name to use combination of device name and device's parent name

uc_pdata->name is populated from device tree property "remoteproc-name".
For those devcices that don't set "remoteproc-name", uc_pdata->name
falls back to dev->name.

If two devices have same name, this will result into uc_pdata->name not
being unique and rproc_init() will fail.

Fix this by using combination of dev->name and dev->parent->name instead
of using just the dev->name to populate uc_pdata->name.
