soc: qcom: smp2p: Use devname for interrupt descriptions
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
