KyongHo Cho b0b6ff0b21 ARM: EXYNOS4: Implement Clock gating for System MMU
This patch includes the implementation of the clock gating
for System MMU. Initially, all System MMUs are not asserted
the system clock. Asserting the system clock to a System MMU
is enabled only when s5p_sysmmu_enable() is called. Likewise,
it is disabled only when s5p_sysmmu_disable() is called.
Therefore, clock gating on System MMUs are still invisible to
the outside of the System MMU driver.

Marek Szyprowski a43efddc3b ARM: S5P: Add function to register gpio interrupt bank data
This patch removes all global data from common s5p gpio interrupt
handler code. This enables to reuse this code on EXYNOS4 platform.
Instead of global data (IRQ_GPIOINT interrupt number,
S5P_GPIOINT_GROUP_MAXNR groups count), a s5p_register_gpioint_bank()
