Subject: [PATCH] Hexagon: Remove useless select of NO_IOPORT_MAP

Hexagon's primary Kconfig entry has a select for NO_IOPORT_MAP. But
because hexagon never defines a Kconfig symbol NO_IOPORT_MAP this select
is a nop. It can be removed.

Perhaps hexagon should add its own Kconfig entry for NO_IOPORT_MAP and
have it default to 'y'. But since no one apparently had any problems
with HAS_IOPORT_MAP defaulting to 'y' on hexagon, as it currently does,
that is unlikely.

Tested by playing with arch/hexagon/configs/comet_defconfig. After "make
oldconfig" the .config contains CONFIG_HAS_IOPORT_MAP=y both before and
after this patch, as is expected.

Actually, the only difference I found in the .config file was that after
this patch the .config file contained
    CONFIG_HEXAGON=y

I have no idea why. Did I botch my test?
