[PATCH 05/15] watchdog/mpcore_wdt: Rename dev to pdev for pointing to struct platform_device

[Viresh Kumar]

Pointer to struct platform_device is named as dev, which makes it confusing when
we write statements like dev->dev to access struct device within it.

This patch renames such names to pdev.
