Tegra30: Add/enable Cardhu build (T30 reference board)

This build is stripped down. It boots to the command prompt.
GPIO is the only peripheral supported. Others TBD.

include/configs/tegra-common.h now holds common config options
for Tegra SoCs.

+ * kernel_addr_r must be within the first 128M of RAM in order for the
+ *   kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
+ *   decompress itself to 0x8000 after the start of RAM, kernel_addr_r
+ *   should not overlap that area, or the kernel will have to copy itself
+ *   somewhere else before decompression. Similarly, the address of any other
+ *   data passed to the kernel shouldn't overlap the start of RAM. Pushing
+ *   this up to 16M allows for a sizable kernel to be decompressed below the
+ *   compressed load address.
+ *
+ * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
+ *   the compressed kernel to be up to 16M too.
+ *
+ * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
+ *   for the FDT/DTB to be up to 1M, which is hopefully plenty.
