A new FPGA HDL has been developed from ADI to support ad354xr
devices.
Add support for ad3541r and ad3542r with following additions:
- use common device_info structures for hs and non hs drivers,
- DMA buffering, use DSPI mode for ad354xr and QSPI for ad355xr,
- change sample rate to respect number of lanes.

Preparing for new parts to be added also in the hs driver,
set model data structures in ad3552r-common.c, to be accessible
from both -hs and non hs driver.

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)

Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.
