i2c: remove sirf bus driver

The CSR SiRF prima2/atlas platforms are getting removed, so this driver
is no longer needed.

-I2C for SiRFprimaII platforms
-
-Required properties :
-- compatible : Must be "sirf,prima2-i2c"
-- reg: physical base address of the controller and length of memory mapped
-     region.
-- interrupts: interrupt number to the cpu.
-
-Optional properties:
-- clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz.
-  The absence of the property indicates the default frequency 100 kHz.
-
-Examples :
-
-i2c0: i2c@b00e0000 {
-    compatible = "sirf,prima2-i2c";
-    reg = <0xb00e0000 0x10000>;
-    interrupts = <24>;
-};
