treewide: replace '---help---' with 'help' in Kconfig files ...

In Linux, '---help---' was deprecated in favor of 'help', and
this is checked by the recent checkpatch.pl

See Linux commit 84af7a6

The number of '---help---' is gradually decreasing in Linux, but there
are still lots. However, '---help---' will be completely killed when
the time comes.

Fortunately, there are only some in Barebox. Replacing them is not hard.

  mtd: spi-nor: Use the spi_mem_xx() API

  The spi_mem_xxx() API has been introduced to replace the
  spi_flash_read() one. Make use of it so we can get rid of
  spi_flash_read().

  Note that using spi_mem_xx() also simplifies the code because this API
  takes care of using the regular spi_sync() interface when the optimized
  ->mem_ops interface is not implemented by the controller.

mtd: m25p80: Fix Kconfig dependencies ...

The m25p80 driver now depends on MTD_SPI_NOR which is disabled in all
defconfigs, so this effectively disables the m25p80 driver in all
defconfigs. Fix this by selecting MTD_SPI_NOR which is library code
without further dependencies. Also let m25p80 depend on SPI because
it needs the SPI code and won't link without it.

mtd: m25p80: use the SPI nor framework ...

Use the spi-nor framework for the m25p80 driver to de-duplicate the code base
and follow along with the linux kernel version, so bugfixes or features can be
easier integrated.

Based on the Linux v4.1-rc3 version of m25p80.c.

mtd: add mtdram device (which build mtd over ram area - useful for FRAM oder MRAM) ...

Change since v1 (Sascha, thanks for review):
	* use xzalloc instead of kzalloc and control check
	* correct help and names
	* fix coding style issue
	* remove verbose and unneeded messages

This adds support for MTD in RAM devices (like FRAM or MRAM).

m25p80: re-import it againt mtd_add_host ...

so we now create the cdev via mtd

This will also simplify sync with linux

to avoid the m25p8000 or m25p00 the cdev is still named name m25p and the
drivers m25p80
