powerpc/40x: Remove stale PTE_ATOMIC_UPDATES macro
[ Upstream commit cc8ee288f484a2a59c01ccd4d8a417d6ed3466e3 ]
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.
Fixes: 2c74e2586bb9 ("powerpc/40x: Rework 40x PTE access and TLB miss")
