irqchip/gic-v3-its: Remove usage of the deprecated ida_simple_xx() API

ida_alloc() and ida_free() should be used instead of the deprecated
ida_simple_get() and ida_simple_remove().

The upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_max() is inclusive. Adjust the code accordingly.
