iio: dac: ad3552r-common: fix ad3541/2r ranges
[ Upstream commit 1e758b613212b6964518a67939535910b5aee831 ]
Fix ad3541/2r voltage ranges to be as per ad3542r datasheet,
rev. C, table 38 (page 57).
The wrong ad354xr ranges was generating erroneous Vpp output.
In more details:
- fix wrong number of ranges, they are 5 ranges, not 6,
- remove non-existent 0-3V range,
- adjust order, since ad3552r_find_range() get a wrong index,
producing a wrong Vpp as output.
Retested all the ranges on real hardware, EVALAD3542RFMCZ:
adi,output-range-microvolt (fdt):
<(000000) (2500000)>; ok (Rfbx1, switch 10)
<(000000) (5000000)>; ok (Rfbx1, switch 10)
<(000000) (10000000)>; ok (Rfbx1, switch 10)
<(-5000000) (5000000)>; ok (Rfbx2, switch +/- 5)
<(-2500000) (7500000)>; ok (Rfbx2, switch -2.5/7.5)
