Both in exynos4 and exynos5, FIMD IP has 3 interrupts in the order: "fifo", "vsync", and "lcd_sys". But The FIMD driver expects the "vsync" interrupt to be mentioned as the 1st parameter in the FIMD DT node. So to meet this expectation of the driver, the FIMD DT node was forced to be made by keeping "vsync" as the 1st paramter. For example in exynos4, the FIMD DT node has interrupt numbers mentioned as <11, 1> <11, 0> <11, 2> keeping "vsync" as the 1st paramter. This patch fixes the above mentioned "hack" of re-ordering of the FIMD interrupt numbers by getting interrupt resource of FIMD by using platform_get_resource_byname().
