Subject: [PATCH v2 0/5] Add support for pressure sensor Bosch BMP580

This patchset adds support for the new pressure sensors BMP580 extending
the bmp280 driver.

Patch 1 introduces a variant enumeration and refactors sensor verification
logic adding a chip_id field to the chip_info struct. This change is
required because BMP380 and BMP580 have the same chip_id and values would
collide using the chip_id as the driver_data value.
Patch 2 introduces new preinit callback and unifies init logic across all
supported variants.
Patch 3 extends the bmp280 driver with the new logic to read measurements
and configure the operation parameters for the BMP580 sensors.
Patch 4 updates the devicetree binding docs with the new sensor id.
Patch 5 adds the NVMEM operations to read and program the NVM user range
contained in the non-volatile memory of the BMP580 sensors.

Changes in V2:
* For patch 3, fixed missing retcodes reported by the kernel test robot.
* For patch 5, fixed logic paths that left the sensor mutex locked
  reported by the kernel test robot.
