ice: Update to 1.42.5-k

- Removes duplicate E825C printout
- Fixes a package download issue with E830
- Updates mentions of E830-XXV to E830-L
- Fix FW logging on load issue by limiting the setting of FW log masks
  and other global configuration to just the first PF of the controller
- Update ice_hw_autogen.h with timesync registers (unused in this
  driver)
- Fix possible overflow condition in NVM access function
- Blocks RDMA load on E830 devices
