iio: filter: admv8818: Force initialization of SDO
commit cc2c3540d9477a9931fb0fd851fcaeba524a5b35 upstream.
When a weak pull-up is present on the SDO line, regmap_update_bits fails
to write both the SOFTRESET and SDOACTIVE bits because it incorrectly
reads them as already set.
Since the soft reset disables the SDO line, performing a
read-modify-write operation on ADI_SPI_CONFIG_A to enable the SDO line
doesn't make sense. This change directly writes to the register instead
of using regmap_update_bits.
Fixes: f34fe888ad05 ("iio:filter:admv8818: add support for ADMV8818")
