Add nodes for Thermal Management Unit to exynos5410.dtsi. Use the same
compatible as for Exynos5420 however without second base for TRIMINFO
register.

Please use GIC_SPI instead of 0 on these.

Exynos5420 has 5 TMU channels and you are adding only 4 so I guess this
is another difference with Exynos5410 besides the TRIMINFO register not
being misplaced? Probably is worth to mention it in the commit message.

Anyway, the patch looks good to me.

Yes, indeed there is no GPU thermal zone. I'll mention it.
