Release 1.1.0

Support of allocating contiguous memory by the driver

• Memory is allocated by the kernel module (and not by the user space like SG model), using dma_alloc_coherent.
• mmap is provided to map memory:
  • Uses virt_to_phys to return the corresponding physical address.
  • Calls remap_pfn_range of the physical memory.
• Set mask to DMA_BIT_MASK(32) supported by cards.
• Added IOCTL_CRONO_LOCK_CONTIG_BUFFER and IOCTL_CRONO_UNLOCK_CONTIG_BUFFER.
• Renamed CRONO_BUFFER_INFO to be CRONO_SG_BUFFER_INFO.
