mtd: maps: remove dead select of MTD_CFI_BE_BYTE_SWAP

'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.

From a previous conversation, it was decided to remove the select entirely:

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