net/hns3: remove some unused capabilities

This patch deletes some unused capabilities, include:
1. Delete some unused firmware capabilities definition, which are:
   UDP_GSO, ATR, INT_QL, SIMPLE_BD, TX_PUSH, FEC and PAUSE.
2. Delete some unused driver capabilities definition, which are:
   UDP_GSO, TX_PUSH.
3. Also redefine HNS3_DEV_SUPPORT_*  as enum type, and change some of
   the values. Note: the HNS3_DEV_SUPPORT_* values is used only inside
   the driver, so it's safe to change the values.
