powerpc/5200: Don't specify IRQF_SHARED in PSC UART driver

commit d9f0c5f9bc74f16d0ea0f6c518b209e48783a796 upstream.

The MPC5200 PSC device is wired up to a dedicated interrupt line
which is never shared.  This patch removes the IRQF_SHARED flag
from the request_irq() call which eliminates the "IRQF_DISABLED
is not guaranteed on shared IRQs" warning message from the console
output.
