With CONFIG_USE_IRQ and DEBUG macro defined,
display_text_info function in board_f.c
printed stack address for IRQ and FIQ.
This code originally came from arch/arm/lib/board.c
and seems specific for ARM for now.
Global variables IRQ_STACK_START and FIQ_STACK_START
are set in interrupt_init function.
The function display_text_info is called from board_init_f,
while interrupt_init is called from board_init_r.
So, display_text_info always resulted in just printing initial
values of IRQ_STACK_START and FIQ_STACK_START as follows:
IRQ Stack: 0badc0de
FIQ Stack: 0badc0de
It is almost meaningless information because 0x0badc0de
is a hard-coded value in arch/arm/cpu/$(CPU)/start.S.
This commit deletes the stack info display code from display_text_info.
And adds new function display_interrupt_info in board_init_r.
