In the initial implementation a number of PMBUS_x_WARN_LIMITs were
mapped to MFR fields. This was incorrect as these MFR limits reflect the
rated limit as opposed to a limit which will generate warning. Instead
return -ENXIO like we were already doing for other WARN_LIMITs.

Subsequently these rated limits have been exposed generically as new
fields in the sysfs ABI so the values are still available.

The core will now start out of reset at boot as soon as clocking is
available. Hence, by the time we unmask the interrupts we already might
have some of them set. Thus, it's important to handle them in the
natural order the core generates them. Otherwise, we could process
'ADI_IRQ_SRC_PWM_CHANGED' before 'ADI_IRQ_SRC_TEMP_INCREASE' and
erroneously set 'update_tacho_params' to true.

APML is also referred as the sideband interface (SBI).

APML is used to communicate with the
Side-Band Remote Management Interface (SB-RMI) which provides
Soft Mailbox messages to manage power consumption and
power limits of the CPU socket.

- This module add support to read power consumption,
