40x TLB handlers were reworked by commit 2c74e2586bb9 ("powerpc/40x: Rework 40x PTE access and TLB miss") to not require PTE_ATOMIC_UPDATES anymore. Then commit 4e1df545e2fa ("powerpc/pgtable: Drop PTE_ATOMIC_UPDATES") removed all code related to PTE_ATOMIC_UPDATES. Remove left over PTE_ATOMIC_UPDATES macro.
