* isl29018 - add support for isl29023 and isl29035

* bmc150 - additional part support (BMI055 accelerometer part, BMA255,
BMA222E, BMA250E and BMA280). Different resolutions but otherwise similar
parts.
* bma180 - add BMA250 (note different from the BMA250E support above despite
the naming). A lot of driver reworking lead up to this - described below.
New features
* kxcjk1013 - add threshold event support.
* rockchip - document DT bindings.
* isl29018 - ACPI support
* bma180 - enable use without IRQ
Cleanups
* Tree wide - drop owner field assignment if using the module_platform_driver
helper as that assigns it anyway.
* kxcjk1013 - drop a redundant assignment of the current range and fix a
a defined but not used warning.
* inv_mpu6050 - Remove an unnecessary cast form a void pointer.
* rockchip - drop and unused variable.
* at91_adc - make a local function static.
* st-sensors-core - correctly handle an error in setting in
st_sensors_set_drdy_int_pin
* isl29018 - typo fix
* bmc150 - fix incorrect scale value for 16G range (Driver new this cycle)
* bmc150 - fix issues when CONFIG_PM_RUNTIME not set (Driver new this cycle)
* ad7606 - line length tidy up.
* bmg160 - set power state only if PM_RUNTIME is defined.
* ak8975 - fix some unnecessary casting between char * and const char *
* bma180 - prefix remaining bits and bobs with bma180_ and ensure consistent.
- use a bool instead of an int for state (as its either on or off).
- expose the temperature channel
- statically allocate buffers to avoid need for update_scan_mode
callback.
- refactor to allow futher chip variants including support for part
specific config and disable code + different resolutions.

The RCU pathwalk fixes end up fixing a couple of cases where we
incorrectly dropped out of RCU walking, due to incorrect initialization
and testing of the sequence locks in some corner cases. Since dropping
out of RCU walk mode forces the slow locked accesses, those corner cases
slowed down quite dramatically.
