mailbox: zynqmp: Remove invalid __percpu annotation in zynqmp_ipi_probe()

commit 170a264d2611a0bfa96b7818730473db5e7546fc upstream.

struct zynqmp_ipi_pdata __percpu *pdata is not a per-cpu variable,
so it should not be annotated with __percpu annotation.

Remove invalid __percpu annotation to fix several
