netvsp: gdma driver advertises eqe 135 capabilities to the soc

[erfrimod]

Now that OpenHCL handles the EQE 135, the Gdma driver should let the SoC know that it has that capability.

• Adding consts for the flags, matching those in Gdma Driver.
• Gdma driver now advertises support for SELF_RESET_ON_EQE_NOTIFICATION (EQE 135 handler)
• Gdma driver now advertises support for VTL2_REVOKE_SUB_ON_RESET_EQE (default behavior of EQE 135)
  • In a follow-up PR, the EQE 135 handler may decide whether to revoke VTL0 VF based on additional context.
• PF Capabilities are logged for a possible benefit to future investigations.
• EQE 135 handler sets HWC timeout to 0, matching Linux mana driver behavior. The HWC is gone, so no point waiting for responses.
• Unit test of EQE handler enhanced to validate the timeout improvement.

Pull request overview

Updates the MANA GDMA VF driver to advertise EQE 135-related capabilities to the SoC/PF and adjusts teardown behavior after VF reconfiguration events (EQE 135), with accompanying test coverage updates.

Changes:

• Advertise additional GDMA driver capability flags (SELF_RESET_ON_EQE_NOTIFICATION, VTL2_REVOKE_SUB_ON_RESET_EQE).
• Log PF capability flags returned by VERIFY_VF_DRIVER_VERSION.
• Treat EQE 135 as “HWC no longer responsive” by setting the HWC timeout to 0 and extending the unit test to validate the new behavior.

File	Description
vm/devices/net/mana_driver/src/tests.rs	Enhances the EQE 135 test to assert timeout changes and HWC failure behavior during teardown.
vm/devices/net/mana_driver/src/gdma_driver.rs	Advertises new caps, logs PF caps, sets HWC timeout to 0 on EQE 135, and tweaks deregister timeout handling; adds test-only getters.
vm/devices/net/gdma_defs/src/lib.rs	Adds missing capability flag constants used by the driver and for PF capability logging.

Tested on a lab machine, these are the socmana logs which show the SoC sees the updated capabilities falgs:
