86809173ce Input: matrix-keymap - fix building keymaps
Keymaps used by drivers based on matrix-keymap facilities are arrays of
unsigned shorts, not chars. Treating them otherwise produces corrupted
keymaps.

b45c8f35a7 Input: matrix-keymap - wire up device tree support
When platform keymap is not supplied to matrix_keypad_build_keymap()
and device tree support is enabled, try locating specified property
and load keymap from it. If property name is not defined, try using
"linux,keymap".

Based on earlier patch by Viresh Kumar <viresh.kumar@st.com>

Change matrix-keymap helper to be out-of-line, like sparse keymap,

and prepare for device tree support.
