[U-Boot] [PATCH] dts: keep clock-names and clocks in SPL DTB if SPL_CLK is enabled
These two properties are necessary for SPL to get clocks from DT.
Note: For now, only clock look-up by index is supported (clk_get_by_index() function), so "clock-names" is never parsed in U-Boot. However, we may want to support something like clk_get_by_name() in the future, so let's keep "clock-names" as well as "clocks".

Simon,
Any comment on this patch?
