[PATCH] x86/ACPI: Insert missing newlines into FACS error messages

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Booting Xen as a PVH guest currently yields:

  (XEN) ACPI: SLEEP INFO: pm1x_cnt[1:b004,1:0], pm1x_evt[1:b000,1:0]
  (XEN) ACPI: FACS is not 64-byte aligned: 0xfc001010<2>ACPI: 
wakeup_vec[fc00101c], vec_size[20]
  (XEN) ACPI: Local APIC address 0xfee00000

Insert newlines as appropriate.

Fixes: d3faf9badf52 ("[host s3] Retrieve necessary sleep information from 
plain-text ACPI tables (FADT/FACS), and keep one hypercall remained for sleep 
notification.")
Fixes: 0f089bbf43ec ("x86/ACPI: fix S3 wakeup vector mapping")

As to why the FACS is misaligned, clearly that is a bug in the domain builder
for PVH guests, but I don't have time to go debugging.
