The C0(mpu_clk), C1(main_clk), and C2(dbg_base_clk) outputs from the main
PLL go through a pre-divider before coming into the system. These registers
were hidden for the CycloneV platform, but are now used for the ArriaV
platform.
This patch updates the clock driver to read the div-reg property for the
socfpga-periph-clk clocks. Also moves the div_mask define to clk.h for re-use.

The clk-phase property is used to represent the 2 clock phase values that is
needed for the SD/MMC driver. Add a prepare function to the clk_ops, that will
use the syscon driver to set sdmmc_clk's phase shift that is located in the
system manager.

v9: none
v8: Use degrees in the clk-phase binding property
v7: Add dts property to represent the clk phase of the sdmmc_clk. Add a
prepare function to the gate clk that will toggle clock phase setting.
Remove the "altr,socfpga-sdmmc-sdr-clk" clock type.
v6: Add a new clock type "altr,socfpga-sdmmc-sdr-clk" that will be used to
set the phase shift settings.
v5: Use the "snps,dw-mshc" binding
v4: Use the sdmmc_clk prepare function to set the phase shift settings
v3: Not use the syscon driver because as of 3.13-rc1, the syscon driver is
loaded after the clock driver.
v2: Use the syscon driver

Move the different kinds of clocks into their own files. The reason is to aid
readability of the code. This also goes along with the other SoC-specific
clock drivers.
The split introduces new structs for the three types of clocks and uses them.
Other changes are not done to the code.
