Add IIC groups clock and reset entries to CPG driver.
IIC Group A consists of IIC0 and IIC1. IIC Group B consists of
IIC2 and IIC3. To confuse things, IIC_PCLK0 is used by group A
and IIC_PCLK1 is used by group B.

CMU_MFCMSCL clock domain provides clocks for MFC (Multi-Format Codec),
JPEG Codec and Scaler IP-cores. According to Exynos850 TRM, CMU_MFCMSCL
generates MFC, M2M, MCSC and JPEG clocks for BLK_MFCMSCL.
This patch adds next clocks:
- bus clocks in CMU_TOP for CMU_MFCMSCL
- all internal CMU_MFCMSCL clocks
- leaf clocks for MFCMSCL, TZPC (TrustZone Protection Controller),
JPEG codec, M2M (Memory-to-Memory), MCSC (Multi-Channel Scaler),
MFC (Multi-Format Codec), PPMU (Platform Performance Monitoring
Unit), SysMMU and SysReg
MFCMSCL related gate clocks in CMU_TOP were marked as CLK_IS_CRITICAL,
because:
1. All of those have to be enabled in order to read
/sys/kernel/debug/clk/clk_summary file
2. When some user driver (e.g. exynos-sysmmu) disables some derived
leaf clock, it can lead to CMU_TOP clocks disable, which then makes
the system hang. To prevent that, the CLK_IS_CRITICAL flag is used,
as CLK_IGNORE_UNUSED is not enough.

CMU_AUD clock domain provides clocks for ABOX IP-core (audio subsystem).
According to Exynos850 TRM, CMU_AUD generates Cortex-A32 clock, bus
clock and audio clocks for BLK_AUD.
This patch adds next clocks:
- bus clocks in CMU_TOP needed for CMU_AUD
- all internal CMU_AUD clocks
- leaf clocks for Cortex-A32, Speedy FM, UAIF0..UAIF6 (Unified Audio

DAP (Debug Access Port), I2S Codec MCLK, D_TZPC (TrustZone
Protection Controller), GPIO, PPMU (Platform Performance Monitoring
Unit), SysMMU, SysReg and WDT
ABOX clock was marked as CLK_IGNORE_UNUSED, as system hangs on boot
otherwise. Once ABOX driver is implemented, maybe it can be handled
there instead.

TREX D Core and P core clocks seem to be related to the BTS (Bus Traffic
Shaper) inside the Exynos7885 SoC, and are needed for the SoC to
function correctly.
When clocks are cut from TREX D Core, the eMMC and the framebuffer stops
working properly. Other unknown things may stop working as well.
When clocks are cut from TREX P Core, the system locks up needing a hard
reset.
Add these clocks and mark them critical so that they are always on.
