Tegra KBC driver have the default key mapping for 16x8 configuration.
The key mapping can be provided through platform data or through DT
and the mapping varies from platform to platform, hence this default
mapping is not so useful. Remove the default mapping to reduce the code
lines of the driver.
The NVIDIA's Tegra KBC has maximum 24 pins to make matrix keypad.
Any pin can be configured as row or column. The maximum column pin
can be 8 and maximum row pin can be 16.
Remove the assumption that all first 16 pins will be used as row
and remaining as columns and Add the property for configurin
Use devm_* for memory, clock, input device allocation. This reduces
code for freeing these resources.

Introduce DT overlay support.
Using this functionality it is possible to dynamically overlay a part of
the kernel's tree with another tree that's been dynamically loaded.
It is also possible to remove node and properties.

The following patchset introduces Device Tree overlays, a method

Enable the generation of symbol & fixup information for
usage with dynamic DT loading.
Passing the -@ option generates a __symbols__ node at the
root node of the resulting blob for any node labels used.
