Since the SoC accepts input frequencies in a wide range from 12 to 50 MHz, boards with different oscillator/crystal frequencies may be built. This patch allows setting a different input frequency in the board specific files to support boards with oscillator/crystal frequencies other than 24 MHz. Changelog: v3: Move board information structure to common.h as it is required for other SoCs as well. v2: Pass reference clock information as part of a structure instead of passing it as a number.
