md: remove CONFIG_MD_RAID_RESHAPE config option.

This was only needed when the code was experimental.  Most of it
is well tested now, so the option is no longer useful.

-        bool "Support adding drives to a raid-5 array"
-        depends on MD_RAID456
-        default y
-        ---help---
-          A RAID-5 set can be expanded by adding extra drives. This
-          requires "restriping" the array which means (almost) every
-          block must be written to a different place.
-
-          This option allows such restriping to be done while the array
-          is online.
-
-          You will need mdadm version 2.4.1 or later to use this
-          feature safely.  During the early stage of reshape there is
-          a critical section where live data is being over-written.  A
-          crash during this time needs extra care for recovery.  The
-          newer mdadm takes a copy of the data in the critical section
-          and will restore it, if necessary, after a crash.
-
-          The mdadm usage is e.g.
-               mdadm --grow /dev/md1 --raid-disks=6
-          to grow '/dev/md1' to having 6 disks.
-
-          Note: The array can only be expanded, not contracted.
-          There should be enough spares already present to make the new
-          array workable.
