Move the ack_intr() method into 'struct ide_port_ops', also renaming it to
test_irq() while at it...

There are now two methods that clear the port interrupt: ack_intr() method,
implemented only on M680x0 machines, that is called at the start of ide_intr(),
and clear_irq() method, that is called somewhat later in this function. In
order to stop this duplication, delegate the task of clearing the interrupt
to clear_irq() method, only leaving to ack_intr() the task of testing for the
port interrupt.

Remove interrupt bit test (not trusted anyway) from siimage_io_dma_test_irq()
and siimage_mmio_dma_test_irq() -- this allows to replace the former function
with now identical ide_dma_test_irq()...

Convert the driver's two dma_end() methods into clear_irq() methods -- the
driver will now use the standard dma_end() method implementation, ide_dma_end().

Now the clear_irq() method is called only from ide_intr() but ide_timer_expiry()
also should call this method in case when drive_is_ready() succeeds...

Fix several errors and warnings given by checkpatch.pl:
- space between the asterisk and parameter name;
- inconsistent spacing between operator and operands;
- space between *sizeof* and open parenthesis;
- #include <asm/io.h> instead of #include <linux/io.h>
- use of *typedef* instead of a structure tag;
- line over 80 characters.
In addition to these changes, also do the following:
- indent with tabs instead of spaces;
- put the function's result type and name/parameters on the same line;
- join back the needlessly broken lines;
- get rid of needless type cast in sgiioc4_checkirq();
- remove space between the type cast and the variable name;
- remove commented out field initializer;
- uppercase the acronyms, lowercase the normal words in the comments;
- fix up the multi-line comment style...

* Add 'unsigned long port_flags' field to ide_hwif_t.
* Add IDE_PFLAG_PROBING port flag and keep it set during probing.
* Fix ide_pio_need_iordy() to not enable IORDY at a probe time
(IORDY may lead to controller lock up on certain controllers
if the port is not occupied).
Loosely based on the recent libata's fix by Tejun, thanks to Alan
for the hint that IDE may also need it.

Add ide_pio_need_iordy() helper and convert host drivers to use it.
This fixes it8172, it8213, pdc202xx_old, piix, slc90e66 and siimage
host drivers to handle IORDY correctly.

git commit 0a0c5168 "PM: Introduce functions for suspending and resuming
device interrupts" introduced some helper functions. However these
functions are only available for architectures which support
GENERIC_HARDIRQS.
Other architectures will see this build error:
drivers/built-in.o: In function `sysdev_suspend':
(.text+0x15138): undefined reference to `check_wakeup_irqs'
drivers/built-in.o: In function `device_power_up':
(.text+0x1cb66): undefined reference to `resume_device_irqs'
drivers/built-in.o: In function `device_power_down':
(.text+0x1cb92): undefined reference to `suspend_device_irqs'
To fix this add some empty inline functions for !GENERIC_HARDIRQS.

The *_nvs_* routines in swsusp.c make use of the io*map()
functions, which are only provided for HAS_IOMEM, thus
breaking compilation if HAS_IOMEM is not set. Fix this
by moving the *_nvs_* routines into hibernate_nvs.c, which
is only compiled if HAS_IOMEM is set.
