H A Dtime.cdiff 575fb69ef919c49283d3fa0d8b13af34011f4abd Sun Mar 08 15:22:06 CET 2020 afzal mohammed <afzal.mohd.ma@gmail.com> ARM: 8966/1: rpc: replace setup_irq() by request_irq()

request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.

Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.

Hence replace setup_irq() by request_irq().
