[Intel-gfx] [PATCH i-g-t] list-workarounds: Don't add an already present platform

[Damien Lespiau]

Currently if we come across several sites that say that a specific
workaround is implemented for a platform, we just add the platform
several times to the list. eg.

WaFbcDisableDpfcClockGating: ivb, hsw, ivb, hsw

This patch prevent that by only adding the plaform if it's not already
there.
