ARM: s3c64xx: dt: Fix boot failure due to double clock initialization
Commit 4178bac ARM: call of_clk_init from default time_init handler added implicit call to of_clk_init() from default time_init callback, but it did not change platforms calling it from other callbacks, despite of not having custom time_init callbacks. This caused double clock initialization on such platforms, leading to boot failures. An example of such platform is mach-s3c64xx. This patch fixes boot failure on s3c64xx by dropping custom init_irq callback, which had a call to of_clk_init() and moving system reset initialization to init_machine callback. This allows us to have clocks initialized properly without a need to have custom init_time or init_irq callbacks.
