Convert remaining interrupt flags SA_* to IRQF_* style.

Documentation/feature-removal-schedule.txt tells us:

What:    Interrupt only SA_* flags
When:    Januar 2007
Why:    The interrupt related SA_* flags are replaced by 
IRQF_* to move them
     out of the signal namespace.

and in linux/interrupt.h regarding SA_* we find

"Migration helpers. Scheduled for removal in 1/2007 Do not 
use for new code !"

Current -rt patches remove SA_* already, so seems to be time 
to convert all OMAP stuff.

In attachment there are 12 patches for this (feel free to 
regroup them):

01 plat-omap directory conversion
02 mach-omap1 directory conversion
(Note: mach-omap2 has no SA_*)
03 ads7846 conversion
04 omap-ts directory conversion
05 i2c-chips directory conversion
06 rtc-omap conversion
07 tsc2102 conversion
08 musbhsdma conversion
09 tahvo-usb conversion
10 omap-rtc conversion
11 innovator-ps2 conversion
12 omap16xxcam conversion

Cheers
