ARM: dts: cros-ec-keyboard: Use keymap macros

The common cros-ec keymap has been defined as macros. This patch uses
the macros to simply linux,keymap in cros-ec-keyboard.dtsi file.

This patch also creates an alias for keyboard-controller to make it
easier to override the keymap in board-specific dts later.

ARM: dts: cros-ec-keyboard: Add alternate keymap for KEY_LEFTMETA

On newer keyboards this key is in a different place. Add both options to
the keymap so that both new and old keyboards work.

ARM: dts: Create a cros-ec-keyboard fragment

All ChromeOS ARM devices that have the standard "CrOS EC" have the
same keyboard mapping. It's silly to include this same definition
everywhere. Let's create a "dtsi" fragment that we can include from
many different boards.

This fragment is based on what's currently in tegra124-venice2.dts
