powerpc/mpc52xx: Properly update irq_desc when set_type() is called.
The MPC5200 PIC driver doesn't correctly update the .status field of
the irq_desc structure when the set_type hook is called. This patch
adds the required code.
Also cleans up the external IRQ typename field to be something easier
to read (very minor).
