[PATCH] Remove blkmtd

Remove the blkmtd driver.

- An alternative exists (block2mtd) that hasn't had  bug report for > 1 year.

- Most embedded people tend to use ancient kernels with custom patches from
  mtd cvs and elsewhere, so the 1 year warning period neither helps nor hurts
  them too much.

- It's in the way of klibc.  The problems caused by pulling blkmtd support
  are fairly low, while the problems caused by delaying klibc can be fairly
  substantial.  At best, this would be a severe burden on hpa's time.
