Use the newer RUNTIME_PM_OPS() macro instead of SET_RUNTIME_PM_OPS()
together with pm_ptr(), which allows us dropping ugly __maybe_unused
attributes.
This optimizes slightly when CONFIG_PM is disabled, too.

Using of_property_read_bool() for non-boolean properties has been
deprecated in favour of of_property_present() and since commit
c141ecc3ce ("of: Warn when of_property_read_bool() is used on
non-boolean properties") this also generates a warning:
OF: /soc@0/soundwire@3330000/wcd9380-tx@0,3: Read of boolean property 'qcom,tx-port-mapping' with a value.
Switch to using of_property_present() to look for "qcom,tx-port-mapping"
properties.

Device has up to WCD939X_MAX_TX_SWR_PORTS (or WCD939X_MAX_RX_SWR_PORTS
for sink) number of ports and the array assigned to prop.src_dpn_prop
and prop.sink_dpn_prop has 0..WCD939X_MAX_TX_SWR_PORTS-1 elements. On
the other hand, GENMASK(high, low) creates an inclusive mask between
<high, low>, so we need the mask from 0 up to WCD939X_MAX_TX_SWR_PORTS-1.
Theoretically, too wide mask could cause an out of bounds read in
sdw_get_slave_dpn_prop() in stream.c, however only in the case of buggy
driver, e.g. adding incorrect number of ports via
sdw_stream_add_slave().

Driver does not modify static wcd939x_sdw_ch_info array, so it can be
made const for code safety.

Add Soundwire Slave driver for the WCD9390/WCD9395 Audio Codec.
The WCD9390/WCD9395 Soundwire devices will be used by the
main WCD9390/WCD9395 Audio Codec driver to access registers
and configure Soundwire RX and TX ports.
