This series enables the front (OV5670/INT3479) and rear (OV8858/INT3477)
cameras on the Dell Latitude 5285 2-in-1 under Linux.

Changes since v4 (addressing feedback from Sakari Ailus):
- Patch 1: Drop the data == &spt_i2c_info guard from the probe condition;
the HID (INT3446) + DMI check is already precise enough.
- Patch 2: Revert n_consumers back to int (unsigned int broke the
if (n_consumers < 0) error check on skl_int3472_fill_clk_pdata());
restructure probe so ChromeOS and error cases return early from the
switch and the Windows path follows as straight-line code after it.
- Patch 3: Correct the VIO description in the commit message and code
comment; drop the inaccurate "no enable register" claim and instead
document why VIO is kept always_on (voltage must match VSIO, no direct
consumers).
- Patch 5: Drop the paragraph explaining the VSIO->dovdd mapping from
the commit message (implementation detail belonging in patch 3);
add an explanation for the dvdd/dovdd reorder in supply_names (core
power stable before the I2C passthrough opens).
- Patch 4: Unchanged.

Tested on Ubuntu 25.10, kernel 6.17.0-22-generic. Both cameras working
in Zoom, Chrome, and GNOME Camera via PipeWire.
