41f277be1d dt-bindings: memory-controllers: exynos5422-dmc: Correct example syntax and memory region 
After adding the interrupt properties to Exynos5422 DMC bindings
example, the mapped memory region must be big enough to access
performance counters registers.

Fix also syntax errors (semicolons) and adjust indentation.

40192209b9 dt-bindings: memory-controllers: exynos5422-dmc: Add interrupt mode 
Add description for optional interrupt lines. It provides a new
operation mode, which uses internal performance counters interrupt when
overflow.  This is more reliable than using default polling mode
implemented in devfreq.
