arm: add CONFIG_MACH_TYPE setting and documentation
CONFIG_MACH_TYPE is used to set the machine type number in the common arm code instead of setting it in the board code. Boards with dynamically discoverable machine types can still set the machine type number in the board code. Signed-off-by: Igor Grinberg <grinberg@compulab.co.il>
