rockbox/firmware/target/arm/as3525/button-clip.c, branch master

Change the clipv2 button driver to use fixed delays rather than processor cycle counting.

2016-01-18T21:35:56+00:00

Also introduce a new delay needed for frequency scaling.

Sansa Clip: simplify matrix key scan

2011-12-13T23:12:21+00:00

Merge clipv1/clipv2 code since they use the same 3x3 matrix
clipzip keyscan buttons now work in bootloader
clipplus untouched (no matrix)
