[PATCH v3 0/5] i2c: img-scb: enchancements to support i2c on pistachio

[Sifan Naeem <sifan.naeem@imgtec.com>]

The following patches are required to enchance the existing driver to
support i2c on pistachio.

This patch series depends on the series of fixes posted earlier[1].
The features added in this series were tested with the earlier fixes
in place.

Tested on Pistachio bub and on tz1090 using an Adafruit I2C
Non-Volatile FRAM Breakout (256Kbit / 32KByte) eeprom.

Used i2c buildroot tools to test the eeprom and the other i2c blocks.
Also used dd commands to copy data to and then to dump data from the
eeprom. i2ctransfer was used to test repeated starts and verified
using a scope.
