Tobias Schramm 2f5a242f67 ramips: mt7621: use higher SPI clock speed on Mikrotik rbm11g and rbm33g
Previously the dts were using a value determined by empirical testing,
because of a spi driver/clock bug. The bug was fixed quite some time
ago. 33 MHz is the default clock frequency used by RouterBOOT and thus
safe.
