Subject: [PATCH] unicore32: Remove unneeded Kconfig entry NO_IOPORT_MAP

Architectures only need a Kconfig entry for NO_IOPORT_MAP if it is
possible that its value will be 'y'. For unicore32 its value will always
be 'n', making it pointless. Remove it.

Tested by playing with arch/unicore32/configs/unicore32_defconfig. This
patch made no difference whatsoever to the generated .config file.
Please note that it has
    CONFIG_HAS_IOPORT_MAP=y

set after invoking "make oldconfig" both before and after this patch.
