Unlike other commands (for example, "fatwrite"), ext4write would
interpret the "sizebytes" as decimal number. This is not only
inconsistend and unexpected to most users, it also breaks usage
like this:
tftp ${addr} ${name}
ext4write mmc 0:2 ${addr} ${filename} ${filesize}
Change this to use the standard notation of base 16 input format.

WARNING: this is a change to the user interface!!
