The Tegra PPSB (an peripheral bus) queues writes transactions.
In order to guarantee that writes have completed before a
certain time, a read transaction to a register on the same
bus must be executed.
This is necessary in situations such as when clearing an
interrupt status or enable, so that when
The Tegra i2c driver supports the I2C_M_IGNORE_NAK and hence
returning I2C_FUNC_PROTOCOL_MANGLING as supported functionality.

This patch series having the:
- Handling of late register write due to Tegra PPSB design.
- support for I2C_M_NOSTART
- Use devm_* for all allocation.
