The runtime power management functions are called from the reset handler even
if CONFIG_PM is disabled, leading to a link error:

drivers/staging/built-in.o: In function `atomisp_reset':
(.text+0x4cd1c): undefined reference to `atomisp_runtime_suspend'
drivers/staging/built-in.o: In function `atomisp_reset':

Removing the #ifdef around the PM functions avoids the problem, and
lets us simplify it further. The __maybe_unused annotation is needed
to ensure the compiler can silently drop the unused callbacks.

Introduce the DPAA2 Ethernet driver, which manages Datapath
Network Interface (DPNI) objects discovered on the MC bus.

In addition to DPNIs, the Ethernet driver uses several other
MC objects to build a network interface abstraction: buffer
pools (DPBPs), I/O Portals (DPIOs) and concentrators (DPCONs).

A more detailed description of the driver can be found in the
