In Chrome OS, the keyboard matrix can be split to two groups:
The keymap for the top row keys can be customized based on OEM
preference, while the keymap for the other keys is generic/fixed
across boards.
This patch creates marcos for the keymaps of these two groups, making
it easier to reuse the generic portion of keymap when we override the
keymap in the board-specific dts for custom top row design.

2.26.2
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.

Changes in v3:
- Create an alias for keyboard-controller
Changes in v2:
- Replace CROS_STD_NON_TOP_ROW_KEYMAP with CROS_STD_MAIN_KEYMAP
