Samsung Clock fixes for 3.13-rc7

* Several patches fixing up incorrectly defined register addresses and
  bitfield offsets that could lead to undefined operation when accessing
  respective registers or bitfields.

 1) clk: exynos5250: fix sysmmu_mfc{l,r} gate clocks

 2a) clk: samsung: exynos5250: Fix ACP gate register offset
 2b) clk: samsung: exynos5250: Add MDMA0 clocks
 2c) ARM: dts: exynos5250: Fix MDMA0 clock number

 3) clk: samsung: exynos4: Correct SRC_MFC register

   All three issues have been present since Exynos5250 and Exynos4 clock
   drivers were added by commits 6e3ad268 ("clk: exynos5250:
   register clocks using common clock framework") and e062b571
   ("clk: exynos4: register clocks using common clock framework")
   respectively.

* Patch to fix automatic disabling of Exynos5250 sysreg clock that could
  cause undefined operation of several peripherals, such as USB, I2C,
  MIPI or display block.

 4) clk: samsung: exynos5250: Add CLK_IGNORE_UNUSED flag for the sysreg
    clock

   Present since Exynos5250 clock drivers was added by commits
   6e3ad268 ("clk: exynos5250: register clocks using common clock
   framework").

* Patch fixing compilation warning in clk-exynos-audss driver when
  CONFIG_PM_SLEEP is disabled.

 5) clk: exynos: File scope reg_save array should depend on PM_SLEEP

   Present since the driver was added by commit 1241ef94 ("clk:
   samsung: register audio subsystem clocks using common clock
   framework").
