the ldb clock can be setup in board code (for example set through PLL5).
Update the ldb_clock rate also through board code.
This should be removed, if a clock framework is availiable.

Changes in v2:
- add comment from Eric Nelson
- move ipu_set_ldb_clock() from drivers/video/ipu.h to
imx-common/video.h
- remove g_ldb_clk with ldb_clk.rate, call ldb_clk directly,
instead of using g_ldb_clk
- add Tested-by from Eric Nelson
