risc-v/qemu-rv: Initialize the userleds without late initialization

If CONFIG_BOARD_LATE_INITIALIZE is not selected, the userleds will
not be initialized. The userled initialization is not required to
be done within board_late_initialize(), thus this commit enables
initializing it in board_app_initialize() too.
