Older firmwares still send sensor configuration using a list of
registers with opaque values defined during sensor tuning.
sx9234 and sx9360 sensor on ACPI based devices are concerned.
More schema to configure the sensors will be needed to support devices
designed for windows, like Samsung Galaxy Book2.
Support schema is: "<_HID>.<register_name>". For instance
"STH9324,reg_adv_ctrl2" in:
Scope (\_SB.PCI0.I2C2)
{
Device (SX28)
{
Name (_HID, "STH9324") // _HID: Hardware ID
...
Name (_DSD, Package (0x02) // _DSD: Device-Specific Data
{
ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301") /*
Device Properties for _DSD */,
Package (0x3F)
{
...
Package (0x02)
{
"STH9324,reg_adv_ctrl2",
Zero
},`

struct sx_common_data doesn't have a num_default_regs element so
drop the documentation for it.

This driver only turns the power for some regulators on at probe and off
via a custom devm_add_action_or_reset() callback. The new
devm_regulator_bulk_get_enable() replaces all this boilerplate code.

Before adding new Semtech sensors, move common logic to all Semtech SAR
sensor in its own file:
- interface with IIO subsystem,
- interrupt management,
- channel access conrol,
- event processing.
The change adds a bidirectional interface between sx93xx and sx_common.
The change is quite mechanical, as the impacted functions are moved
and renamed.
