Subject: [PATCH] boards/avr/avrdx/breadxavr: provide board_late_initialize

This patch amends commit f077c0321de which is a part of series that
changed (in commit 48db502daf9) default value of BOARD_LATE_INITIALIZE
to yes. With this change, the boards are required to provide
board_late_initialize function.

Commit f077c0321de added this function to many AVR boards but
not to this one, making the build with default configuration
fail. This patch rectifies that and provides an empty function.

With this patch applied, the build no longer fails.

+ * Name: board_late_initialize
+ *
+ * Description:
+ *   Excerpt from Kconfig:
+ *
+ *   If CONFIG_BOARD_LATE_INITIALIZE is set, board_late_initialize() is
+ *   called after up_initialize() just before the main application is
+ *   started. It can be used to initialize more complex, board-specific
+ *   device drivers.
+ *
+ *   Function runs on a temporary, internal kernel thread and can therefore
+ *   wait for events.
+ *
+ *   Currently, the board has no need for this function but the Kconfig
+ *   option is enabled by default so the function either needs to be defined,
+ *   or default configuration needs to be changed. This is why this function
+ *   exists but is empty.
