[PATCH v1 07/10] Staging: comedi: fix BIT macro issue in das6402.c

[Ravishankar Karkala Mallikarjunayya <ravishankarkm32@gmail.com>]

This patch Replace all occurences of (1<<x) by BIT(x) and DAS6402_CTRL_TRIG(x),
DAS6402_MODE_RANGE(x), DAS6402_MODE_DMA(x) macros in the file das6402.c
to get rid of checkpatch.pl "CHECK" output "Prefer using the BIT macro"
