[v3,04/19] media: ti-vpe: cal: use runtime_resume for errata handling

Commit Message

We need to do errata handling every time CAL is being enabled. The code
is currently in cal_runtime_get(), which is not the correct place for
it.

Move the code to cal_runtime_resume, which is called every time CAL is
enabled.
