ata: pata_ftide010: Add missing MODULE_DESCRIPTION

Add the missing MODULE_DESCRIPTION() to avoid warnings such as:

WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/ata/pata_ftide010.o

when compiling with W=1.

ata: pata_ftide010: Convert to platform remove callback returning void

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

ata: Explicitly include correct DT includes

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.

ata: pata_ftide010: Remove build dependency on OF

The pata_ftide010 can be built without CONFIG_OF being enabled, as long
as the macro of_match_ptr() is not used when initializing the platform
driver .of_match_table field.

Remove the use of this macro and the build dependency on OF.

ata: Drop commas after OF match table sentinels

It does not make sense to have a comma after a sentinel, as any new

The DMA is broken on this specific device for some unknown

port information around in probe while we're at it.

ata: Add driver for Faraday Technology FTIDE010

This adds a driver for the Faraday Technology FTIDE010
PATA IP block.

When used with the Storlink/Storm/Cortina Systems Gemini
SoC, the PATA interface is accompanied by a PATA<->SATA
bridge, so while the device appear as a PATA controller,
it attaches physically to SATA disks, and also has a
designated memory area with registers to set up the bridge.

The Gemini SATA bridge is separated into its own driver
file to make things modular and make it possible to reuse
the PATA driver as stand-alone on other systems than the
Gemini.
