Sascha Hauer b75c015143 ARM i.MX: Add common clock support for 2bit gate 
This gate consists of two bits:

0b00: clk disabled
0b01: clk enabled in run mode and disabled in sleep mode
0b11: clk enabled

Currently only disabled and enabled are supported. As it's unlikely
that we find something like this in another SoC create a i.MX specific
clk helper for this.

Sascha Hauer 2af9e6db14 ARM i.MX: Add common clock support for pllv1 
The pllv1 is found on i.MX1, i.M25, i.MX27, i.MX31 and i.MX35.
Currently only reading the rate is supported.

Sascha Hauer 6c7b06850c ARM i.MX: prepare for common clock framework 
- Add necessary #ifdefs for CONFIG_COMMON_CLOCK
- Add a global spinlock to protect the CCM registers
