[U-Boot] [PATCH 1/2] arm: fix displaying IRQ stack info

[Masahiro Yamada]

With CONFIG_USE_IRQ and DEBUG macro defined,
display_banner function printed stack address
for IRQ and FIQ.

Global variables IRQ_STACK_START and FIQ_STACK_START
are set in interrupt_init function.

The function display_banner is called from board_init_f,
while interrupt_init is called from board_init_r.

So, display_banner 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 moves the stack info display code
after interrupt_init call.
