Broadcom stb bsc iic master controller

Required properties:

- compatible: should be "brcm,brcmstb-i2c" or "brcm,brcmper-i2c"
- clock-frequency: 32-bit decimal value of iic master clock freqency in Hz
		   valid values are 375000, 390000, 187500, 200000
		   93750, 97500, 46875 and 50000
- reg: specifies the base physical address and size of the registers

Optional properties :

- interrupt-parent: specifies the phandle to the parent interrupt controller
  this one is cascaded from
- interrupts: specifies the interrupt number, the irq line to be used
- interrupt-names: Interrupt name string

Example:

bsca: i2c@f0406200 {
      clock-frequency = <390000>;
      compatible = "brcm,brcmstb-i2c";
      interrupt-parent = <&irq0_intc>;
      reg = <0xf0406200 0x58>;
      interrupts = <0x18>;
      interrupt-names = "upg_bsca";
};
