The Denx MA5D4 dts doesn't properly define the slow_xtal and main_xtal frequencies, the PMC then has to fallback to using the RC oscillators whose precision is not really good.
As both crystals are populated, define their frequencies, see p17 of http://www.denx-cs.de/sites/all/files/MA5D4.HWM_.002.pdf
Also, remove the obsolete main_clock definition.
