General help message cleanup
Many of the help messages were not really helpful; for example, many

were actually redundant.

those too can be somewhat expensive depending on the board.

This patch removes all references to the direct CFI FLASH interface
(via flash_info[]). Now that all FLASH types currently handled in
mtdparts are available (if selected, see below) via the MTD infrastructure.
This is NOR, NAND and OneNAND right now. This can be achieved by defining
the following options:
CONFIG_MTD_DEVICE (for all FLASH types)
plus
CONFIG_FLASH_CFI_MTD (for NOR FLASH)
So we need to add those defines to the board config headers currently

we shouldn't break mtdparts compatibility.
One big advantage from this solution is that the cmd_mtdparts.c is
*much* cleaner now. Lot's of #ifdef's are removed and the code itself
is smaller. Additionally the newly added MDT concatenation feature
can new be used via the mtdparts infrastructure and therefor via

initialized SDRAM TLB (detected by EPN=0). This TLB will not be
cleared. This TLB doesn't need to be TLB #0, this RAM-booting
version will detect it and preserve it. So booting via BDI2000
will work and booting with a complete different TLB init via
