[PATCH v2 0/2] irqchip/gic-v3-its: Mark ITS tables as decrypted

[Steven Price]

These two patches were taken from the larger series to support running
Linux as a realm guest in CCA[1]. They add support to the GIC for
allocating the ITS pages such that they are decrypted so that the host
can access then for emulation purposes.

Note that there are likely to be future changes to make this more
configurable in the future, as it's possible that in a future
configuration a protected component within the realm could take on the
emulation responsibilities ('Planes support')[2]. But this is a good
building block for the future.
