dedirpog: add a parameter 'spispeed' to set the SPI clock rate
The following rates are
available (in Hz):
375k, 750k, 1.5M, 2.18M, 3M, 8M, 12M and 24M
The original driver reinitializes the programmer after setting the
speed, so the initialization calls have moved into a new function
dediprog_setup() which is called twice.
Corresponding to flashrom svn r1649.
