mpc85xx_edac: Make L2 interrupt shared too
The other two interrupt handlers in this driver are shared, except this
one. When loading the driver, it fails like this.
So make the IRQ line shared.
Freescale(R) MPC85xx EDAC driver, (C) 2006 Montavista Software
mpc85xx_mc_err_probe: No ECC DIMMs discovered
EDAC DEVICE0: Giving out device to module MPC85xx_edac controller mpc85xx_l2_err: DEV mpc85xx_l2_err (INTERRUPT)
genirq: Flags mismatch irq 16. 00000000 ([EDAC] L2 err) vs. 00000080 ([EDAC] PCI err)
mpc85xx_l2_err_probe: Unable to request irq 16 for MPC85xx L2 err
remove_proc_entry: removing non-empty directory 'irq/16', leaking at least 'aerdrv'
