ZRAM is being disabled on tuivm due to observed stability issues due to
ZRAM's use of GFP_MEMALLOC. Increase maximum movable zone size to
compensate.
When kswapd swaps out pages, PF_MEMALLOC is set, which results in zram
ignoring the min_watermark, and lowmem_reserve. This is problematic
because we intend for movable memory to stay in ZONE_MOVABLE, rather
than falling back to ZONE_NORMAL. If the later occurs to such a high
degree that all ZONE_NORMAL memory is consumed, as is observed to be
the case during a "C2PA" testcase, attempts to plug in additional
ZONE_MOVABLE memory may fail due to requiring a small amount of
GFP_KERNEL memory.

"qcom,initial-movable-zone-size" creates a movable zone of the given size
before userspace starts. This is useful in a system where a userspace
component (psi-daemon) is used to hotplug in memory on a on-demand basis.
With swap disabled, the current tvm carveout size (68 Mb) hits
out-of-memory condition before psi-deamon is started.
Once psi-daemon is running, it detects the number of blocks added to the
movable zone via "qti_virtio_mem/kernel_plugged" sysfs file, and
can reduce or increment the number as necessary.

This property describes how large of a movable zone should be created
when the virtio_mem device probes.
Also, fix all errors reported by make dt_binding_check.

The virtio-mem device has always had a dependency on mem-buf for plugging
in memory. Previously, the ordering was not a concern, since hotplug was
not done until userspace was up. However, in subsequent patches we
will instead hotplug in memory as soon as the virtio-mem device probes.

Add NVMEM cells FMD_CNT2_STOP and FMD_CHG_PON for supporting
Find-My-Device(FMD) feature.
- FMD_CNT2_STOP controls the number of FMD cycles after which the
feature will auto disable to save power in OFF mode.
- FMD_CHG_PON can be use to disable USB PON feature for testing
purpose.
