[PATCH v3 07/52] xen/arm64: prepare for moving MMU related code from head.S

[Penny Zheng <Penny.Zheng@xxxxxxx>]

From: Wei Chen <wei.chen@xxxxxxx>

We want to reuse head.S for MPU systems, but there are some
code are implemented for MMU systems only. We will move such
code to another MMU specific file. But before that we will
do some indentations fix in this patch to make them be easier
for reviewing:
1. Fix the indentations of code comments.
2. Fix the indentations for .text.header section.
3. Rename puts() to asm_puts() for global export
