[PATCH v3 0/3] Add I2C support to Broadcom iProc

This patchset contains the initial I2C support for Broadcom 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 (100 kHz) and fast mode (400 kHz)

Changes from v2:
- Have the I2C driver default to y so it does not need to be selected from
ARCH_BCM_IPROC. This also helps to get rid of one patch. The driver still
depends on ARCH_BCM_IPROC
- Get rid of redundant check on resource returned by platform_get_resource

Changes from v1:
- Fix function argument parenthesis
- Get rid of redundant driver owner field
