Log Message:
gicv3: ITS: Add support for indirect device tables.

When devbits is too large to fit into the first level of device table,
some hardware supports the concept of indirect tables. Add support for
this and use it when supported.

This is required for MSIs to work properly on Snapdragon X Elite platforms
(otherwise, MAPD command fails and stalls the ITS command queue).
