ARM: S3C2440: CPUFREQ: Add crystal frequency Kconfig entries.
Add entries to select the crystal to select for each different supported board. This information is then available for anything else requiring this, such as the CPUFreq PLL tables. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
