[PATCH] mailbox: zynqmp-ipi: drop irq_to_desc() call

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

irq_to_desc() is not exported to loadable modules, so this driver now
fails to link in some configurations:

ERROR: modpost: "irq_to_desc" [drivers/mailbox/zynqmp-ipi-mailbox.ko] undefined!

I can't see a purpose for this call, since the return value is unused
and probably left over from some code refactoring.

Address the link failure by just removing the line.

Fixes: 6ffb1635341b ("mailbox: zynqmp: handle SGI for shared IPI")
