Remove git_cpu_init()

Please check and ack your platforms. One difference for many platforms is that we rely on TF-A or the previous boot stage to initialize the GIC. I assume some unintended copy & paste error has led most platforms to reinitialize the GIC. If I'm wrong in that assumption, we'll see how we can fix it.

Seems fine, but while testing I ran into a panic() on plat-k3, seems to be caused by a different GIC cleanup:

@glneo, I'm trying to address the issue you mention in #6516

[clementfaure]

I got a crash at boot on old ARMv7 platforms imx-mx6qsabresd

I will have a look at it tomorrow

[clementfaure]

Actually, the issue comes from this commit : 69171be where vers = 1 on imx6qsabresd. Cortex-A9 i.MX platforms feature GICv1.

[jenswikl]

@glneo and @clementfaure does the updated #6516 fix your issues?

[clementfaure]

@jenswi-linaro Yes, I can boot the board now (imx8qmmek was also affected).

[sahilnxp]

I was getting the panic while booting on LX2160A-RDB platforms with this pull request.
But after #6516 is merged, board is booting fine.

Rebased on master to get the fix from #6516, tags applied and commit messages updated to use imperative mood.

[jenswikl]

A few commits still miss an A-B or R-B tag. I think we can wait a little longer before merging.

For the plat-ti it looks good (not sure if this actually changes anything, so not sure it could break anything), but I haven't gotten around to testing, only a visual code review: Reviewed-by: Andrew Davis <afd@ti.com>
