Update iProc I2C binding document to add new compatible string
"brcm,iproc-nic-i2c". Optional property "brcm,ape-hsls-addr-mask" is
also added that allows configuration of the host view into the APE's
address for "brcm,iproc-nic-i2c"

Update the binding document to make the 'interrupts' property optional.
For certain revisions of the I2C controller (e.g., iProc NIC I2C), I2C
interrupt is unwired to the interrupt controller. In such case, this
'interrupts' property should be left unspecified, and driver will fall
back to polling mode

Add initial support to the Broadcom iProc I2C controller found in the
iProc family of SoCs.
The iProc I2C controller has separate internal TX and RX FIFOs, each has
a size of 64 bytes. The iProc I2C controller supports two bus speeds
including standard mode (100kHz) and fast mode (400kHz)
