ARM: OMAP AM33XX: clock data: SET_RATE_PARENT in lcd path
LCDC clock node is a one that does not have set rate capability. It just passes on the rate that is sent downstream by it's parent. While lcdc clock parent and it's grand parent - dpll_disp_m2_ck and dpll_disp_ck has the capability to configure rate. And the default rates provided by LCDC clock's ancestors are not sufficient to obtain pixel clock for current LCDC use cases, hence currently display would not work on AM335x SoC's (with driver modifications in platfrom independent way). Hence inform clock framework to propogate set rate for LCDC clock as well as it's parent - dpll_disp_m2_ck. With this change, set rate on LCDC clock would get propogated till dpll_disp_ck via dpll_disp_m2_ck, hence allowing the driver (same driver is used in DaVinci too) to set rates using LCDC clock without worrying about platform dependent clock details.
