net: enetc: add support for the "Update" operation to buffer pool table
The buffer pool table contains buffer pool configuration and operational
information. Each entry corresponds to a buffer pool. The Entry ID value
represents the buffer pool ID to access.
The buffer pool table is a static bounded index table, buffer pools are
always present and enabled. It only supports Update and Query operations,
This patch only adds ntmp_bpt_update_entry() helper to support updating
the specified entry of the buffer pool table. Query action to the table
will be added in the future.
