Sylwester Nawrocki a701fe3851 clk: exynos4: Add CLK_GET_RATE_NOCACHE flag for the Exynos4x12 ISP clocks
The ISP clock registers belong to the ISP power domain and may change
their values if this power domain is switched off/on. Add
CLK_GET_RATE_NOCACHE flags to ensure we do not rely on invalid cached
data when setting or getting frequency of those clocks.

Without this fix the FIMC-IS Cortex-A5 core and AXI bus clocks have
incorrect frequencies, which breaks the ISP operation and starting the
video pipeline fails with timeouts reported by the FIMC-IS firmware.

See related commit 722a860ecb "[media]
exynos4-is: Fix FIMC-IS clocks initialization" for more details.
