Add board include header and defconfig files for Pogoplug V4

Signed-off-by: Tony Dinh mibodhi@gmail.com ---

Changes in v3: - Migrate config symbols from board include header to defconfig - Remove obsolete config symbols from header file - Don't use ifdefs for unselectable config symbols in header file

Changes in v2: - Use canonical format for defconfig file

Note: currently the fdt_get_phy_addr function in this file is duplicate in this board and many other Kirkwood boards (eg. Sheevaplug, GoFlex Home, etc.). This function is being factored out into common area by another patch. And because it was written for flattree only, the patch is being rewritten to use livetree calls.
