clocksource/imx: Fix boot with non-DT systems

Commit 6dd747825b ("ARM: imx: move timer resources into a structure")
moved initialization parameters into a data structure, but neglected to set
the irq field in that data structure for non-DT boots. This causes the system
to hang if a non-DT boot is attempted.
