Replace a magic number for the DDR2/mDDR PHY clock ID with a proper definition. In addition, don't request this clock ID on DA830 hardware, which does not have a DDR2/mDDR PHY (or associated PLL controller).

Hi,
This patch does depend on my earlier patch to tidy up the definition of set_cpu_clk_info() :
Can you please post everything as a series of 4 patches so that we don't add and then replace the magic value with the enum? Other than that, I'm happy with the series and will apply the updated series on Friday or so, thanks!
