[PATCH 1/4] Simplify test for RAM devices

[Jörn Engel]

mtdblock is the only user of aggregate capabilities in mtd.  This is clearly
bogus and should be changed.  In particular, it tries to determine whether
the device in question is a piece of RAM.  For every single driver that fits
the current criteria, an easier test would be to check for the type being
MTD_RAM.
