The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The function returned zero unconditionally, so the function returning an
int is something between useless and irritating. With the goal to make
platform drivers' remove function return void, it's helpful to convert
the function accordingly. This converts several drivers to the new
.remove_new callback that was introduced to smoothen the platform driver
conversion.

Updates to the usual drivers (megaraid_sas, scsi_debug, lpfc, target,
mpi3mr, hisi_sas, arcmsr). The major core change is the
constification of the host templates (which touches everything) along
with other minor fixups and clean ups.

It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

The ports-implemented property is mainly used on the OF-based platforms
with no ports mapping initialized by a bootloader/BIOS firmware. Seeing
the same of_property_read_u32()-based pattern has already been implemented
in the generic AHCI LLDD (glue) driver and in the Mediatek, St AHCI
drivers let's move the property read procedure to the generic
ahci_platform_get_resources() method. Thus we'll have the forced ports
mapping feature supported for each OF-based platform which requires that,
and stop re-implementing the same pattern in there a bit simplifying the
code.

It does not make sense to have a comma after a sentinel, as any new
elements must be added before the sentinel.
Add comments to clarify the purpose of the empty elements.

Add an extra argument to ahci_platform_get_resources(), that is
for the bitmap representing the resource to get in this function.
Currently there is no resources to be defined, so all the callers set
'0' to the argument.
