mb/google/poppy: Add camera devices power sequencing through ACPI power resources
This patch controls the camera devices power through ACPI power resource. * Add Opregions for PMIC, * TI_PMIC_POWER_OPREGION * TI_PMIC_VR_VAL_OPREGION * TI_PMIC_CLK_OPREGION * TI_PMIC_CLK_FREQ_OPREGION * Add power resources for sensors and VCM, * OVTH for CAM0 * OVFI for CAM1 * VCMP for VCM * Implement _ON and _OFF methods for sensor and VCM module's power on and power off sequences. BUG=b:38326541 BRANCH=none TEST=Build and boot poppy. Dump and verify that the generated DSDT table has the required entries.
