ARM64 / ACPI: Ignore the return error value of acpi_map_gic_cpu_interface()
MADT scanning will stop when it gets an error from the handler, acpi_map_gic_cpu_interface(), on arm64. However, we need to find all of the enabled CPUs so that SMP initialization can work properly. So, if an error occurs in this case, ignore it for now so that we can find all of the enabled CPUs. Signed-off-by: Hanjun Guo <hanjun.guo@linaro.org> Signed-off-by: Will Deacon <will.deacon@arm.com>
