350d1ebfce iio: dac: ad3552r-hs: add ad3541/2r support 
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.

67a0f04095 iio: dac: ad3552r: share model data structures 
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.

1e758b6132 iio: dac: ad3552r-common: fix ad3541/2r ranges 
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)

cdd30ebb1b module: Convert symbol namespace to string literal 
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("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.

Scripted using

  git grep -l -e MODULE_IMPORT_NS -e EXPORT_SYMBOL_NS | while read file;
  do
    awk -i inplace '
      /^#define EXPORT_SYMBOL_NS/ {
        gsub(/__stringify\(ns\)/, "ns");
        print;
        next;
