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. Signed-off-by: Tobias Schramm <t.schramm@manjaro.org>
