  DCC(Data Capture and Compare) is a DMA engine designed for debugging purposes.
In case of a system crash or manual software triggers by the user the DCC hardware
stores the value at the register addresses which can be used for debugging purposes.
The DCC driver provides the user with debugfs interface to configure the register
addresses. The options that the DCC hardware provides include reading from registers,
writing to registers, first reading and then writing to registers and looping
through the values of the same register.

This patch series is a continuation of the previous series

The dcc driver is moved to a new location drivers/misc along with the binding
as per discussions.
