[SRU J/K][PATCH V2 1/2] watchdog/hpwdt: Enable HP_WATCHDOG for ARM64 systems.

[Michael Reed]

From: Jerry Hoemann <jerry.hoemann at hpe.com>

Enable HP_WATCHDOG for ARM64 systems.
HPWDT_NMI_DECODING requires X86 as NMI handlers are X86 specific.

Add arm64 option to CONFIG_HP_WATCHDOG

CONFIG_HP_WATCHDOG is used in module hpwdt.  A software monitoring watchdog
and NMI handling driver. This driver will detect lockups and provide
a stack trace. This is a driver that will only load on an HP ProLiant
system with a minimum of iLO2 support.  This option allow it to build
on arm64.
