Subject: [PATCH v3 2/2] media: i2c: change lt6911uxe irq_gpio name to "hpd"

Lt6911uxe is used in IPU6 / x86 platform, worked with an out-of-tree
int3472 patch and upstream intel/ipu6 before. It is only used on ACPI
platforms till now and there are no devicetree bindings for this
driver.

The upstream int3472 driver uses "hpd" instead of "readystat" now.
this patch updates the irq_gpio name to "hpd" accordingly, so that
mere users can now use the upstream version directly without relying
on out-of-tree int3472 pin support.

The new name "hpd" (Hotplug Detect) aligns with common naming
conventions used in other drivers(like adv7604) and documentation.
