clk: imx: add scu clock common part

Browse source

Add SCU clock common part which will be used by client clock drivers.
SCU clocks are totally different from the legacy clocks (No much
legacy things can be reused), it's using a firmware interface now based
on SCU protocol. So a new configuration option CONFIG_MXC_CLK_SCU is added.
