Subject: drm/lima: Clean up redundant pdev pointer
Git-commit: 2ce216edf2c661fd9d2f5e19ce72fd80c25abc64
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

There's no point explicitly tracking the platform device when it can be
trivially derived from the regular device pointer in the couple of
places it's ever used.
