'select' does not work on config options in a 'choice', so currently it is
possible to enable MTD_PHYSMAP_IXP4XX without MTD_CFI_BE_BYTE_SWAP.

Let's replace the select with 'depends on'.

Note that, if we remove the select / dependency, the kernel will compile
with MTD_PHYSMAP_IXP4XX=y and MTD_CFI_BE_BYTE_SWAP=n so if it would be
better to remove the select, please advise as I do not have the hardware
to runtime test this.

This dead select was found by kconfirm, a static analysis tool for Kconfig.
