Enable hpwdt for the rl300, an ARM64 based platform.


Patch 1: watchdog/hpwdt.c: Include nmi.h only if CONFIG_HPWDT_NMI_DECODING

ARM64 does not support NMI and does not have <asm/nmi.h>.  Include
nmi.h only if CONFIG_HPWDT_NMI_DECODING is defined.

Patch 2: watchdog/Kconfig:  Allow hpwdt.c to be built for ARM64.

Allow hpwdt.c to be built for (ARM64 || X86) as this part of hwpdt doesn't
use NMI.

Make HPWDT_NMI_DECODING dependent upon X86 as NMI handlers are specific
to X86 platforms.


== Changes for v2 ==
Update patch documentation.




Jerry Hoemann (2):
  watchdog/hpwdt: Include nmi.h only if CONFIG_HPWDT_NMI_DECODING
  watchdog: Enable HP_WATCHDOG for ARM64 systems.
