arm64: dts: rockchip: yy3588: drop unused wifi_disable regulator

[SuperKali]

The wifi_disable fixed regulator is never used as a supply by anything. It only holds GPIO0_C4 high at boot, and on this board that pin is not a Wi-Fi control at all.

Wi-Fi on the YY3588 is a PCIe RTL8852BE module on its own standby rail, independent of this GPIO. GPIO0_C4 is actually the eDP backlight PWM pin (pwm2_m0). The node was carried over from a radxa reference and just steals that pad.

This drops the node. Wi-Fi and Bluetooth were checked working on the board with the regulator gone.

You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Walkthrough

This change removes the wifi_disable fixed-regulator GPIO node (wifi-disable-gpio-regulator) from the rk3588-youyeetoo-yy3588 device tree source file. The node previously appeared after the vcc12v_dcin regulator definition. No other modifications are present.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Poem
A rabbit hopped through the device tree,
Snipped a node it did not need to see,
No more GPIO for WiFi's disable,
The dts now leaner, clean on the table,
Hop, hop, away—simplicity!
