[PATCH v4 22/36] iio: orientation: hid-sensor-rotation: use local struct device

[Sanjay Chitroda <sanjayembeddedse@gmail.com>]

From: Sanjay Chitroda <sanjayembeddedse@gmail.com>

Introduce a local struct device pointer derived from &pdev->dev.
This avoids repeated &pdev->dev usage and improves readability.
