[ARM] 3053/1: introduce ixp2000_reg_wrb (ixp2000_reg_write plus readback)
Patch from Lennert Buytenhek
Introduce ixp2000_reg_wrb, which is a variant of ixp2000_reg_write
that does a readback from the target register, to make sure that
the write has been flushed out of the write buffer.
Unlike the previous (ineffective) readback in ixp2000_reg_write, this
readback is followed by an instruction that depends on the value of
the readback so that the CPU actually stalls until the readback has
completed.
