Use upstream ODROID N2+ support and CDC ACM cooldown fix (#948)

* Use latest ODROID-N2+ patches (partial #929)

Use the queued patches (and fixes) for upstream ODROID-N2+ support.
This uses the clock settings from meson-g12b-a311d.dtsi running the
CPUs at the following clocks:
- 4xA73@2.2GHz
- 2xA53@1.8GHz

* Actually fix CDC ACM error recovery path (#921)

Remove the revert of the cool-down patch and add the actual fix for
the CDC ACM error recovery path.

HardKernel ODROID-N2+ uses an Amlogic S922X rev. C chip capable of higher
clock speeds than the original ODROID-N2. Hardkernel supports the big cpu
cluster at 2.4GHz and the little cpu cluster at 2.0GHz. Opp points and
regulator changess are from the HardKernel Linux kernel sources.
clock speeds than the original ODROID-N2.
The rev. C support a slighly higher VDDCPU_A & VDDCPU_B voltages and supports
the same OPPs as the Amlogic A311D SoC from the same G12B family.

This adds the missing perpheral clock for the RNG for Amlogic G12. As
stated in amlogic,meson-rng.yaml, this isn't always necessary for the
RNG to function, but is better to have in case the clock is disabled for
some reason prior to loading.

On the odroid N2 plus, cpufreq is not available due to an error on the cpu
regulators. vddcpu a and b get the same PWM. The one provided to vddcpu A
is incorrect. Because vddcpu B PWM is busy the regulator cannot register:

Like on the odroid n2, use PWM A out of GPIOE_2 for vddcpu A to fix the

Subject: [PATCH 14/14] usb: cdc-acm: fix cooldown mechanism
Commit a4e7279cd1d1 ("cdc-acm: introduce a cool down") is causing
regression if there is some USB error, such as -EPROTO.
This has been reported on some samples of the Odroid-N2 using the Combee II
Zibgee USB dongle.
> struct acm *acm = container_of(work, struct acm, work)
is incorrect in case of a delayed work and causes warnings, usually from
the workqueue:
> WARNING: CPU: 0 PID: 0 at kernel/workqueue.c:1474 __queue_work+0x480/0x528.
When this happens, USB eventually stops working completely after a while.
Also the ACM_ERROR_DELAY bit is never set, so the cooldown mechanism
previously introduced cannot be triggered and acm_submit_read_urb() is
never called.
This changes makes the cdc-acm driver use a single delayed work, fixing the
pointer arithmetic in acm_softint() and set the ACM_ERROR_DELAY when the
cooldown mechanism appear to be needed.
