By default, the touchscreen example will call arch_tcinitialize() to
register the touchscreen device before it attempts to open it.

This works well for the typical touchscreen controller but there are
other devices that cannot be initialized and uninitialized in this
fashion. Consider a USB mouse, fo example. The USB mouse will be
fashion. Consider a USB mouse, for example. The USB mouse will be
registered when the mouse is connected and unregistered when the

de-selected, then the arch_tcinitialize() and arch_tcuninitialize() will
never be called.
NOTE also that the functions arch_tcinitialize() and
arch_tcuninitialize() are effective non-standard operating system
calls. This is cheap shortcut and a violation of the OS interface.
You can get away with this in the flat build (CONFIG_BUILD_FLAT),
but not in the protected or kernel builds (CONFIG_BUILD_PROTECTED
or CONFIG)BUILD_KERNEL). In those cases, you will need to perform
one-time touchscreen initialization in board_initialize().
