In order to reduce even further the size of the big
vivid_create_instance() function, let's place the part of the
logic which creates the device nodes into a separate function.

    With this and the past patches, those warnings finally
    vanishes:

The vivid_create_instance() function is too harry. Smatch can't
process it, because it takes too long.

The detection part is an important piece of it. As such, there
are even comments before and after such block.

rc-core kapi uses nanoseconds for infrared durations for receiving, and
microseconds for sending. The uapi already uses microseconds for both,
so this patch does not change the uapi.

Infrared durations do not need nanosecond resolution. IR protocols do not
have durations shorter than about 100 microseconds. Some IR hardware offers
250 microseconds resolution, which is sufficient for most protocols.
Better hardware has 50 microsecond resolution and is enough for every
protocol I am aware off.

Unify on microseconds everywhere. This simplifies the code since less
conversion between microseconds and nanoseconds needs to be done.

This affects:
 - rx_resolution member of struct rc_dev
 - timeout member of struct rc_dev
 - duration member in struct ir_raw_event

Use the same strategies used at v4l2-compat32.c, in order to
solve them and avoid warnings.

As reported by smatch:
	drivers/media/pci/saa7134//saa7134-tvaudio.c:686 saa_dsp_writel() warn: should 'reg << 2' be a 64 bit type?

On a 64-bits Kernel, the shift might be bigger than 32 bits.

In real, this should never happen, but let's shut up the warning.

Instead of calling printk(), use pr_foo() macros.

While here, do some cleanup at the printed messages, as some
has __func__, while others have the module name (sometimes
spelled as "ttusb_dvb").

This driver still uses the USB stack for DMA transfers,
which is broken for a long time. I almost dropped this driver,
as there's a high chance that nobody is using it with upstream
Kernels, as we didn't receive any bug reports.

As fixing this won't be hard, I ended opting to fix.

While here, I dropped an ugly hack that implemented read via
a separate function that was just doing a memcpy().

It should be noticed that, during the init phase, there's
a "b4" register that were never initialized, as its buffer
were used just to store the results of "b3" initialization.

The printk should not be using %d for the number of pages.

After looking better, the real problem here is that the
number of pages should be long int.
