[ Upstream commit c4bce84d0b ]
We added checks to __pa() / __va() to ensure they're only called with
appropriate addresses. But using BUG_ON() is too strong, it means
virt_addr_valid() will BUG when DEBUG_VIRTUAL is enabled.
Instead switch them to warnings, arm64 does the same.
Fixes: 4dd7554a64 ("powerpc/64: Add VIRTUAL_BUG_ON checks for __va and __pa addresses")
