media: atomisp_gmin_platform: Set ELDO1 to 1.6V on devices with an AXP288 PMIC

Browse source

Testing on multiple tablet models has shown that Android always uses
1.6V for ELDO1, adjust our code to match.

This also matches with how ELDO1 is used in the DSDTs on these devices,
where for Cherry Trail (ISP2401) based devices ELDO1 is used for an
ACPI power-resource which is named "P16P".

Note on Bay Trail (ISP2400) based devices the power-resource is called
"P15P", which suggests that 1.5V might be a better value there.
