clk: bcm2835: probe for fixed-clock in device tree
This will allow fixed-clocks to be registered in device tree, which in turn will allow clock clients to look up their clocks in device tree. The first driver to use this feature will be the bcm2835 SDHCI/MMC driver. In the long run, it is likely these fixed clocks will be replaced with an actual clock implementation which speaks to the VideoCore processor, but this change should be transparent to clock consumers.
