clk: exynos5250: Fix parent clock for sclk_mmc{0,1,2,3} commit 688f7d8c9fef ("clk: exynos5250: Fix divider values for sclk_mmc{0,1,2,3}") incorrectly sets the divider for sclk_mmc{0,1,2,3} to fix the wrong clock value. Though this fixed issue with Arndale, it created regressions for other boards like Snow. On Exynos5250, sclk_mmc<n> is generated like below (as per the clock names in drivers/clk/samsung/clk-exynos5250.c) mout_group1_p ==> mout_mmc<n> ==> div_mmc<n> ==> div_mmc_pre<n> => sclk_mmc<n> Earlier div_mmc<n> was set as the parent for sclk_mmc<n>, hence div_mmc_pre<n> was not getting referred in kernel code and depending on its value set during preboot, sclk_mmc<n> value was different for various boards. Setting the correct clock generation path should fix the issues reported in above referenced commit. The changes committed during the earlier patch has also been reverted here.

clk: exynos5250: Add CLK_IGNORE_UNUSED flag for pmu clock Currently 'pmu' clock is not handled by any of the drivers. Also before the introduction of CCF, this clock was not defined, hence was left enabled always. When this clock is disabled, software reset register becomes inaccessible and system reboot doesn't work. Upon restoring the default behaviour, system reboot starts working.
