Subject: [PATCH net-next v2 5/7] net: ipa: pass a platform device to ipa_smp2p_irq_init()

Rather than using the platform device pointer field in the IPA
pointer, pass a platform device pointer to ipa_smp2p_irq_init().
Use that pointer throughout that function (without assuming it's
the same as the IPA platform device pointer).
