ARM: bcm2835: add SDHCI node to DT
Add the SDHCI device node to the SoC DT file. Add a dummy fixed-clock to satisfy the SDHCI driver's clock lookup; eventually this should be replaced by a real clock implementation. Add board specific properties to the Raspberry Pi board file. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
