      Implement memory accessor interface in the MTD layer which enables the
kernel to access flash data.

This patch adds two new members to the mtd_partition structure, a function
handler which will be called during setup of the partition and an argument
to be passed to this setup function.

Example:
+static struct mtd_partition spi_flash_partitions[] = {
+       [0] = {
+               .name       = "U-Boot",
+               .offset     = 0,
+               .size       = SZ_256K,
+               .mask_flags = MTD_WRITEABLE,
+       },
+       [1] = {
+               .name       = "U-Boot Environment",
+               .offset     = MTDPART_OFS_NXTBLK,
+               .size       = SZ_64K,
+               .mask_flags = MTD_WRITEABLE,
+       },
+       [2] = {
+               .name       = "Linux",
+               .offset     = MTDPART_OFS_NXTBLK,
+               .size       = SZ_7M,
+               .mask_flags = 0,
+       },
+       [3] = {
+               .name       = "MAC Address",
+               .offset     = MTDPART_OFS_NXTBLK,
+               .size       = SZ_64K,
+               .mask_flags = 0,
+               .setup      = davinci_get_mac_addr,
+               .context    = (void *)0,
+       },
+};

The davinci_get_mac_addr function reads the MAC address from
offset ZERO of last MTD partition.
