Subject: [PATCH v2 10/33] thermal: exynos: replace tmu_irqstatus check by
 Exynos5440 one

reg->tmu_irqstatus is set to non-zero value only for Exynos5440
so replace check for non-zero value of reg->tmu_irqstatus by
explicitly checking for Exynos5440 SoC type.  Then remove no
longer needed reg->tmu_irqstatus register abstraction.

There should be no functional changes caused by this patch.
