Will Deacon 7ed3cce2fe arm64: mm: Drop 'const' from conditional arm64_dma_phys_limit definition
commit 770093459b9b333380aa71f2c31c60b14895c1df upstream.

Commit 031495635b46 ("arm64: Do not defer reserve_crashkernel() for
platforms with no DMA memory zones") introduced different definitions
for 'arm64_dma_phys_limit' depending on CONFIG_ZONE_DMA{,32} based on
a late suggestion from Pasha. Sadly, this results in a build error when
passing W=1:

  | arch/arm64/mm/init.c:90:19: error: conflicting type qualifiers for 'arm64_dma_phys_limit'

Drop the 'const' for now and use '__ro_after_init' consistently.
