Yanjiang Jin 27bda205ba EDAC, mpc85xx: Implement remove method for the platform driver 
If we execute the below steps without this patch:

  modprobe mpc85xx_edac [The first insmod, everything is well.]
  modprobe -r mpc85xx_edac
  modprobe mpc85xx_edac [insmod again, error happens.]

We would get the error messages as below:

  BUG: recent printk recursion!
  Oops: Kernel access of bad area, sig: 11 [#48]
  Modules linked in: mpc85xx_edac edac_core softdog [last unloaded: mpc85xx_edac]

   system_call

Address this by cleaning up properly when removing the platform driver.

Tested on a T4240QDS board.
