[PATCH RESEND] sparc: remove obsolete config ARCH_ATU

[Lukas Bulwahn]

Before consolidation of commit 4965a68780c5 ("arch: define the
ARCH_DMA_ADDR_T_64BIT config symbol in lib/Kconfig"), the config ARCH_ATU
was used to control the state of the config ARCH_DMA_ADDR_T_64BIT. After
this consolidation, the config ARCH_ATU has been without use and effect.

Remove this obsolete config.
