[U-Boot] [PATCH v4] Separate mtdparts command from jffs2

As it turns out, that split was incomplete or incorrect.

It seems that since commit 68d7d65100 we have two different,
incompatible implementations of mtdparts_init() - one in
common/cmd_jffs2.c and another one in common/cmd_mtdparts.c

When NAND and JFFS2 and MTDPARTS are enabled at the same time, the
mtdparts_init() from common/cmd_mtdparts.c is called, which obviously
does not pereform the required intializations for JFFS2: all JFFS2
related commands just return without any error messages but also
without any useful output either.

Please provide a fix!

Best regards,

Wolfgang Denk
