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.

CONFIG_MACH_TYPE [relevant for ARM only][mandatory]
This setting is mandatory for all boards that have only one
machine type and must be used to specify the machine type
number as it appears in the ARM machine registry
(see http://www.arm.linux.org.uk/developer/machines/).
Only boards that have multiple machine types supported
in a single configuration file and the machine type is
runtime discoverable, do not have to use this setting.
