Add initial support for dynamic frequency scaling of the main NOC
on imx8mq.
Make DDRC the parent of the NOC (using passive governor) so that the
main NOC is automatically scaled together with DDRC by default.
Support for proactive scaling via interconnect will come on top.

the basic peripherals. A customer will then have to modify or append to

This makes sure the clock tree setup for the dphy is not dependent on
other components.
Without this change bringing up the display can fail like

kernel: phy phy-30a00300.dphy.2: for hs_clk/ref_clk=451656000/593999998 ~ 165/217
if LCDIF doesn't set up that part of the clock tree first. This was

BUCK3 needs a regulator-enable-ramp-delay since otherwise the board
freezes on etnaviv probe. With this pgc_gpu suspends and resumes as
expected. This must have been always broken since gpcv2 support was
enabled.
We also enable all the regulators needed for Deep Sleep Mode (DSM) as
always-on:
- VDD_SOC supplied by BUCK1
- VDDA_1P8 supplied by BUCK7
- VDDA_0P9 supplied by LDO4
- VDDA_DRAM supplied by LDO3
- NVCC_DRAM supplied by BUCK8
- VDD_DRAM supplied by BUCK5
Finally LDO5 and LDO6 provide VDD_PHY_1V8 and VDD_PHY_0V9 used by the
SOCs MIPI, HDMI and USB IP cores. While we would in theory be able to
turn these off (and I've tested that or LDO6 and mipi with USB disabled)
it is of little practical use atm since USB doesn't runtime suspend so
let's revisit this at a later point.

Beacon Embeddedworks is launching a development kit based on the
i.MX8M Nano SoC. The kit consists of a System on Module (SOM)
+ baseboard. The SOM has the SoC, eMMC, and Ethernet. The baseboard
has an wm8962 audio CODEC, a PDM microphone, and a single USB OTG.
The baseboard is capable of two different, mutually exclusive video
outputs, so the common items are in the baseboard file. When
the video becomes available, LVDS output will be added to this kit
file, and a second kit file will be added to support HDMI.

Since commit 36e2c7421f02 ("fs: don't allow splice read/write without
explicit ops") we've required that file operation structures explicitly
enable splice support, rather than falling back to the default handlers.
Most /proc files use the indirect 'struct proc_ops' to describe their
file operations, and were fixed up to support splice earlier in commits
40be821d627c..b24c30c67863, but the mountinfo files interact with the
VFS directly using their own 'struct file_operations' and got missed as
a result.
This adds the necessary support for splice to work for /proc/*/mountinfo
and friends.
