clk: samsung: exynos5433: Set NoC (Network On Chip) clocks as critical

Browse source

The ACLK_BUS0/1/2 are used for NoC (Network on Chip). If NoC's clocks are
disabled, the system halt happens. Following clocks must be always enabled:
 - CLK_ACLK_BUS0_400 : NoC's bus clock for PERIC/PERIS/FSYS/MSCL,
 - CLK_ACLK_BUS1_400 : NoC's bus clock for MFC/HEVC/G3D,
 - CLK_ACLK_BUS2_400 : NoC's bus clock for GSCL/DISP/G2D/CAM0/CAM1/ISP.

This patch also adds the CLK_SET_RATE_PARENT flag to the CLK_SCLK_JPEG_MSCL
because this clock should be used for bus frequency scaling. This clock need
to be changed on the fly with CLK_SET_RATE_PARENT flag.
