watchdog: hpwdt: Programable Pretimeout NMI Make whether or not the hpwdt watchdog delivers a pretimeout NMI programable by the user. The underlying iLO hardware is programmable as to whether or not a pre-timeout NMI is delivered to the system before the iLO resets the system. However, the iLO does not allow for programming the length of time that NMI is delivered before the system is reset. By watchdog API, in hpwdt_set_pretimeout a val == 0 disables the NMI. When val != 0, hpwdt_set_pretimeout will enable the pretimeout NMI provided the current timeout is greator than the HW specified pretimeout length. Otherwise an error is returned. In set_timeout, if the new timeout is <= an already established pretimeout, the pretimeout is canceled. This matches the action watchdog_set_timeout in the watchdog core would do if an hpwdt specific set_timeout function wasn't specified.
