On T234 Kfuse is part of the fuse controller, this increases the fuse
block size to 0x20000. Currently, the fuse size is specified as 0x10000
in the device-tree. If a client driver issues tegra_fuse_read APIs with
offsets > 0x10000, then it can result in page fault.
Increase the fuse page size to 0x20000.

Graph sound card driver is enabled by default now and legacy machine
driver is going to be removed. Hence cleanup the legacy bindings and
going forward only maintain the graph sound card bindings. The 'sound'
device for graph card and legacy machine driver were merged earlier,
so we don't require duplicate phandles for the 'sound' node. Hence
remove the 'tegra_sound_graph' phandle.

These preprocessor conditionals were a temporary step to facilitate
step by step reviews. Remove them.
Delete display overlay includes from tegra234-jetson.dts since the
formatting no longer is correct for an overlay. This file
tegra234-jetson.dts is planned for removal in the near future.
Indentation will be fixed in a follow-on patch to make reviews easier.

In this commit:
1. The large platform overlays are being directly built into
a new base "nv" dtb. The names of these new dtbs directly tracks the
name of the upstream dtb that it extends. For an upstream dtb named
<base>.dtb the new corresponding new file is named <base>-nv.dtb.
2. The source files for <base>-nv.dtb are located in the nv-soc/ and
nv-platform/ files. Those files originated in the overlay/
directory but are moved to reflect that they are no longer part of
an overlay.
This new layout seeks to simplify building and handling of dtb files
while retaining close compatibility with the upstream dts sources.
