vxge: Removed accessing non-supported registers.
- Removed accessing GENDMA_INT register - This allowed the firmware to perform a generic DMA write to host memory. This feature is not supported by the ASIC, this patch removes access to GENDMA_INT register. Signed-off-by: Sreenivasa Honnur <sreenivasa.honnur@neterion.com> Signed-off-by: David S.
