Subject: [PATCHv11 14/19] x86/acpi: Rename fields in acpi_madt_multiproc_wakeup structure

In order to support MADT wakeup structure version 1, provide more
appropriate names for the fields in the structure.

Rename 'mailbox_version' to 'version'. This field signifies the version
of the structure and the related protocols, rather than the version of
the mailbox. This field has not been utilized in the code thus far.

Rename 'base_address' to 'mailbox_address' to clarify the kind of
address it represents. In version 1, the structure includes the reset
vector address. Clear and distinct naming helps to prevent any
confusion.
