[U-Boot] [PATCH v2 1/2] arm: include config.h in arch/arm/lib/vectors.S

[Masahiro Yamada]

Commit 41623c91 moved exception handling to arch/arm/lib/vectors.S,
but it missed to include <config.h>.

This mistake causes two problems.

[1]
"enbw_cmc", "da850evm_direct_nor", "calimain" boards are broken.

They expect CONFIG_SYS_DV_NOR_BOOT_CFG (= 0x00000011) at the beginning
of the boot image.

But it is missing since commit 41623c91 because
CONFIG_SYS_DV_NOR_BOOT_CFG is never defined in arch/arm/lib/vectors.S.

[2]
Boards with CONFIG_USE_IRQ fail with undefined reference error
of "IRQ_STACK_START" and "FIQ_STACK_START".

This is _potential_ problem because currently there is no board
enabling CONFIG_USE_IRQ.
But we cannot deny the possibility some board may enable it in future.

(If we are not willing to support interrupt feature, all references
to CONFIG_USE_IRQ should be dropped immediately.)
