[PATCH 1/5] arm: enable allocate-on-read for LPAE's DCACHE_WRITEBACK

[Ard Biesheuvel <ardb@kernel.org>]

The LPAE version of DCACHE_WRITEBACK is currently defined as no-allocate
for both reads and writes, which deviates from the non-LPAE definition,
and mostly defeats the purpose of enabling the caches in the first place.

So align LPAE with !LPAE, and enable allocate-on-read.
