ASoC: soc-acpi: make some variables of acpi adr and link adr non-const 

Currently, we use predefined snd_soc_acpi_link_adr tables to match the
link adr from ACPI table to select the machine driver and the topology.
However, with the mechanism, we need to create the snd_soc_acpi_link_adr
table for each audio config. The sof_sdw machine driver is used by
almost all Intel platforms with SOF and we can load required topology
file dynamically today. In other words, we can use sof_sdw machine
driver as the default machine driver for Intel SOF SoundWire codecs and
no need to create snd_soc_acpi_link_adr table for every new audio
configs.
To achieve it, we need to drop the const for some members and edit the
link adr and acpi adr data to match the data from the ACPI table.
