Bartosz Golaszewski a31b4dcf18 clk: davinci: remove support for da830
This SoC has some leftover code all over the kernel but no boards are
supported anymore. Remove support for da830 from the davinci clock
driver. With it: remove the ifdefs around the data structures as the
da850 remains the only davinci SoC supported and the only user of this
driver.
