memory: tegra: Add support for multiple IRQs
Add support to handle multiple MC interrupts lines, as supported by
Tegra264. Turn the single IRQ handler callback into a counted array to
allow specifying a separate handler for each interrupt. Move IRQ
handlers into tegra_mc_soc struct, so as to specify SoC specific
values.
