dim: make DIMLIB dependent on NET

DIMLIB's capabilities are supplied by the dim, net_dim, and
rdma_dim objects, and dim's interfaces solely act as a base for
net_dim and rdma_dim and are not explicitly used anywhere else.
rdma_dim is utilized by the infiniband driver, while net_dim
is for network devices, excluding the soc/fsl driver.

In this patch, net_dim relies on some NET's interfaces, thus
DIMLIB needs to explicitly depend on the NET Kconfig.

The soc/fsl driver uses the functions provided by net_dim, so
it also needs to depend on NET.

soc: fsl: select FSL_GUTS driver for DPIO

The soc/fsl/dpio driver will perform a soc_device_match()
to determine the optimal cache settings for a given CPU core.

If FSL_GUTS is not enabled, this search will fail and
the driver will not configure cache stashing for the given
DPIO, and a string of "unknown SoC" messages will appear:

fsl_mc_dpio dpio.7: unknown SoC version
fsl_mc_dpio dpio.6: unknown SoC version
fsl_mc_dpio dpio.5: unknown SoC version

soc: fsl: dpio: add Net DIM integration

Use the generic dynamic interrupt moderation (dim) framework to
implement adaptive interrupt coalescing on Rx. With the per-packet
interrupt scheme, a high interrupt rate has been noted for moderate
traffic flows leading to high CPU utilization.

The dpio driver exports new functions to enable/disable adaptive IRQ
coalescing on a DPIO object, to query the state or to update Net DIM
with a new set of bytes and frames dequeued.

The NXP's QorIQ processors based on ARM Core have RCPM module

Note that this driver will not support PowerPC based QorIQ processors,
and it depends on PM wakeup source framework which provide collect
wake information.

This patch adds DPAA2 MC and AIOP console log support.

The platform driver probes on the "fsl,dpaa2-console" device tree node
which describes the base firmware address needed in order to infer the
start address of both firmware logs: MC and AIOP.
It then exports two misc char devices which can be used to dump
the needed logs.

soc: fsl: add GUTS driver for QorIQ platforms

The global utilities block controls power management, I/O device
enabling, power-onreset(POR) configuration monitoring, alternate
function selection for multiplexed signals,and clock control.

This patch adds a driver to manage and access global utilities block.
Initially only reading SVR and registering soc device are supported.
Other guts accesses, such as reading RCW, should eventually be moved
into this driver as well.
