MAINTAINERS: Remove Tomasz from Samsung clock and pinctrl entries

I have been no longer at Samsung for a long time, the platforms
that I am knowledgable about (S3C24xx, S3C64xx, Exynos 4) are no longer
relevant and we have people with better capabilities as maintainers
already, so let me remove myself. Thanks for the nice collaboration
everyone!
