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.

@ -154,11 +154,18 @@ return virtual addresses to userspace from a 48-bit range.
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
