[PATCH v3 09/12] xen: rename p2m_ipa_bits to p2m_gpa_bits

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

The IPA terminology is Arm-specific, so rename p2m_ipa_bits to
p2m_gpa_bits to use architecture-neutral naming in
xen/common/device-tree/ code.

No functional changes.

Changes in v3:
 - Introduce #define p2m_gpa_bits p2m_ipa_bits for Arm instead of
   renaming of p2m_ipa_bits to p2m_gpa_bits to keep Arm part of
   changes clearer and keep using Arm-specific terminolgy inside
   Arm code.
---
Changes in v2:
 - New patch.
