msm: smp2p: Convert smp2p irq register base from virtual to physical

Virtual base address of smp2p irq register is hardcoded in device
tree which causes issues with LPAE support, and irq register is
referenced by name, which adds overhead.

Change to physical address in device tree and ioremap to virtual address.
Reference irq register by index as opposed to by name.
