docs: arm64: Fix indentation and doc formatting
Sphinx generates the following warnings for the arm64 doc pages: Documentation/arm64/memory.rst:158: WARNING: Unexpected indentation. Documentation/arm64/memory.rst:162: WARNING: Unexpected indentation. These indentations warnings can be resolved by utilising code hightlighting instead.

Software can "opt-in" to receiving VAs from a 52-bit space by
specifying an mmap hint parameter that is larger than 48-bit.
+
For example:
- maybe_high_address = mmap(~0UL, size, prot, flags,...);
+
+.. code-block:: c
+
+ maybe_high_address = mmap(~0UL, size, prot, flags,...);
It is also possible to build a debug kernel that returns addresses
from a 52-bit space by enabling the following kernel config options:
+
+.. code-block:: sh
+
CONFIG_EXPERT=y && CONFIG_ARM64_FORCE_52BIT=y
Note that this option is only intended for debugging applications
