ub: add config device ops in ubcore

driver inclusion
category: feature
bugzilla: NA
CVE: NA

--------------------------------

config_device is a function pointer
and a member of the ubcore_ops_t structure.
When the ubcore_register_device interface is invoked,
the vendor driver registers with the UB protocol stack.
The administrator or cloud management system
uses uvs-admin or uvs to invoke the UB protocol stack
to provide a device configuration interface for tools.
The UB protocol stack invokes this interface
to configure basic device information through drivers.

Input parameter:
dev: contains vendor-defined private device data.
cfg: configuration information.
The UBN driver obtains information from this field for configuration.
timeout: specifies the timeout interval, in ms.
