Fix TRAB channel switching delay for trab_fkt.bin standalone applikation
Patch by Martin Krause, 08 Nov 2005
In tsc2000_read_channel() the delay after setting the multiplexer
to a temperature channel is increased from 1,5 ms to 10 ms. This
is to allow the multiplexer inputs to stabilize after huge steps
of the input signal level.
