i915: Remove GLES 3.0 sRGB workaround.

Gen3 doesn't support GLES 3.0, so there's no need for it.

- * Fixes up the context for GLES23 with our default-to-sRGB-capable behavior
- * on window system framebuffers.
- *
- * Desktop GL is fairly reasonable in its handling of sRGB: You can ask if
- * your renderbuffer can do sRGB encode, and you can flip a switch that does
- * sRGB encode if the renderbuffer can handle it.  You can ask specifically
- * for a visual where you're guaranteed to be capable, but it turns out that
- * everyone just makes all their ARGB8888 visuals capable and doesn't offer
- * incapable ones, becuase there's no difference between the two in resources
- * used.  Applications thus get built that accidentally rely on the default
- * visual choice being sRGB, so we make ours sRGB capable.  Everything sounds
- * great...
- *
- * But for GLES2/3, they decided that it was silly to not turn on sRGB encode
- * for sRGB renderbuffers you made with the GL_EXT_texture_sRGB equivalent.
- * So they removed the enable knob and made it "if the renderbuffer is sRGB
- * capable, do sRGB encode".  Then, for your window system renderbuffers, you
- * can ask for sRGB visuals and get sRGB encode, or not ask for sRGB visuals
- * and get no sRGB encode (assuming that both kinds of visual are available).
- * Thus our choice to support sRGB by default on our visuals for desktop would
- * result in broken rendering of GLES apps that aren't expecting sRGB encode.
- *
- * Unfortunately, renderbuffer setup happens before a context is created.  So
- * in intel_screen.c we always set up sRGB, and here, if you're a GLES2/3
- * context (without an sRGB visual, though we don't have sRGB visuals exposed
- * yet), we go turn that back off before anyone finds out.
