hwmon: (pmbus/adm1266) seed timestamp from the real-time clock

adm1266_set_rtc() seeds the chip's SET_RTC register from
ktime_get_seconds(), which returns CLOCK_MONOTONIC -- i.e. seconds
since the host last booted, not seconds since the Unix epoch.

The chip stamps that value into every blackbox record it captures.
Userspace reading those timestamps back expects wall-clock seconds:
that's what the SET_RTC frame layout documents (datasheet Rev. D,
Table 84) and what every other consumer of "seconds since epoch"
assumes.  Seeding from CLOCK_MONOTONIC gives blackbox records a
timestamp that is only meaningful within a single boot of the host
and silently resets to small values on every reboot.

Switch to ktime_get_real_seconds() so the seed matches what the
register is documented to hold.
