ARM: uniphier: support eMMC boot for PH1-LD11 and PH1-LD20

The Boot ROM on PH1-LD11/LD20 exports built-in APIs to load images
from an eMMC device. They are useful to reduce the memory footprint
of SPL, rather than compiling the whole MMC framework.

Commit d085ecd61b99 ("ARM: uniphier: switch to raw U-Boot image")
claimed that u-boot-with-spl.bin would be useful in its commit log,
but it was not available because the commit missed to define
CONFIG_SPL_MAX_SIZE. Without it, CONFIG_SPL_PAD_TO is not defined
either (see include/config_fallbacks.h). So, the SPL image is not
padded correctly.

ARM: uniphier: switch to raw U-Boot image

Now everything is done to load a raw U-Boot proper image instead of
an mkimage-processed one (as far as I tested on NAND, eMMC, NOR).

The SPL already knows the load address of the U-Boot proper without
parsing its uImage header because the load address is defined by
CONFIG_SYS_TEXT_BASE, assuming that the two images are generated from
the same build.

My main motivation of this switch is to use u-boot-with-spl.bin, a
concatenation of u-boot-spl.bin and u-boot.bin. (I wish there were
a concatenation of u-boot-spl.bin and u-boot.img...) Anyway, this
commit would be useful for one-shot image burn.

The Boot ROM expects the boot image (SPL) in the Boot Partition 1.
So, updating images involves the hardware partition switch. It might

To be user-friendly, this commit adds a useful command to update the

the TFTP server and execute "run emmcupdate" from the command line.
