apm821xx: switch MyBook Live's recovery images to multi-file

This patch converts the MyBook Live's recovery image to utilize the
multi-image method which integrates the device-tree binary directly
into the image.

The new initramfs can be loaded through the MyBook Live's U-boot
in the following way:

=> setenv ipaddr 192.168.1.1
=> setenv serverip 192.168.1.2
=> sata init; run addtty; tftp $kernel_addr_r wd_mybooklive-initramfs.bin; bootm
   Waiting for PHY auto negotiation to complete... done
   ENET Speed is 1000 Mbps - FULL duplex connection (EMAC0)
   Using ppc_4xx_eth0 device
   TFTP from server 192.168.1.2; our IP address is 192.168.1.1
   Filename 'wd_mybooklive-initramfs.bin'.
