Refactor the MIPI camera driver to support two ACPI device generation
modes via a Kconfig choice:
1. Windows/Linux mode (MIPI_ACPI_TYPE_WINDOWS_LINUX): Generates a
single ACPI device for the camera sensor and any associated VCM or
NVM devices on the same I2C bus. The IPU ACPI device is attached to
the iGPU, not standalone. This is the preferred method for Windows
and mainline Linux.
2. ChromeOS mode (MIPI_ACPI_TYPE_CHROMEOS): Generates separate ACPI
devices for each camera component (sensor, CIO2, VCM, NVM). The IPU
ACPI device is generated separately from the iGPU. This maintains
compatibility with the existing ChromeOS-style setup.
The implementation uses runtime conditionals to select between the two
modes. Common helper functions are shared between modes, while device-
specific logic is conditional based on the selected ACPI type.
The default selection is MIPI_ACPI_TYPE_CHROMEOS for ChromeOS builds and
MIPI_ACPI_TYPE_WINDOWS_LINUX otherwise.
