Subject: [PATCH 2/3] irqchip/gicv3-its: remove GITS_BASER_TYPE_CPU base on latest spec

In the latest specification(version 24.0), clause 5.12.13 GITS_BASERn.
The meaning of value=0x3 in "Type" field was revised to reserved. As
below:
0x3. Reserved.

In the early versions(like 19.0), it defined as below:
0x3. Physical Processors.
