ARM: uniphier: add emmcupdate command
The Boot ROM expects the boot image (SPL) in the Boot Partition 1.
So, updating images involves the hardware partition switch. It might
be a bit advanced for some users.
To be user-friendly, this commit adds a useful command to update the
images; just put SPL and U-Boot proper into the public directory of
the TFTP server and execute "run emmcupdate" from the command line.
