memory: tegra: Apply interrupts mask per SoC
Currently we are enabling handling of interrupts specific to Tegra124+ which happen to overlap with previous generations. Let's specify interrupts mask per SoC generation for consistency and in a preparation of squashing of Tegra20 driver into the common one that will enable handling of GART faults which may be undesirable by newer generations.
