Subject: [PATCH 1/3] ARM: decompress: remove unused ARCH_HAS_DECOMP_WDOG

ARCH_HAS_DECOMP_WDOG is only used in lib/inflate.c which is not
included in arch/arm/boot/compressed/decompress.c now.  That said,
ARCH_HAS_DECOMP_WDOG is not used at all.  Let's remove it.

Subject: [PATCH 2/3] ARM: remove unused arch_decomp_wdog()

With ARCH_HAS_DECOMP_WDOG removed from arch/arm/boot/compressed/decompress.c,
all the arch_decomp_wdog() definition at platform level is unneeded.
Remmove it.

Subject: [PATCH 3/3] ARM: samsung: remove unused arch_decomp_wdog() code

Besides the fact that CONFIG_S3C_BOOT_WATCHDOG is defined nowhere, with
ARCH_HAS_DECOMP_WDOG removed from arch/arm/boot/compressed/decompress.c,
all the arch_decomp_wdog() related code is not used.  Remove them.
