When using /proc/interrupts to collect statistics on smp2p interrupt
counts, it is hard to distinguish the different instances of smp2p from
each other. For example to debug a processor boot issue, the ready and
handover interrupts are checked for sanity to ensure the firmware
reached a specific initialization stage.

Remove "smp2p" string from the irq request so that the irq will default
to the device name. Add an .irq_print_chip() callback to print the irq
chip name as the device name. These two changes allow for a unique name
to be used in /proc/interrupts as shown below.

/ # cat /proc/interrupts | grep smp2p
 18:  ...      ipcc 196610 Edge      smp2p-adsp
 20:  ...      ipcc 131074 Edge      smp2p-modem
170:  ...  smp2p-modem   1 Edge      q6v5 ready
178:  ...  smp2p-adsp   1 Edge      q6v5 ready
