This patch increases the SPI clock speed on the rbm11g and rbm33g to
33 MHz. Initially it was set to a empirically determined value.
The bug necessitating the empirical testing has since been resolved.
33 MHz is the default used by RouterBOOT. It is well within spec of
the SPI flashes used. I've also verified that signal integrity is not
an issue, the clock edges are still pretty good.
v2 removes the m25p,fast-read property from the dts since it is not
required until 50 MHz.
