kernel: Move Romulus to ColdFire FSI driver

This bumps the kernel to incldue a commit that switches to the ColdFire
FSI driver.

Benjamin Herrenschmidt (1):
      arm: dts: aspeed: Romulus can use coprocessor for FSI

A note to developers: from here on you must use an initrd that includes
the ast-cf-fsi.bin firmware, or FSI will not function. See commit
'openpower: Add ColdFire firmware to initrd'.
