In commit 0270d74ef8862350 we switched from ppcuic_init() to directly
creating the UIC device, but I missed that the Bamboo's UIC has a
non-standard DCR base register value (0xc0 rather than the default
of 0x30). This made Linux panic early in the boot process.
Specify the correct dcr-base property value when creating the UIC.

With this fix Nathan's test case goes on to eventually hit
a QEMU assert:
qemu-system-ppc: ../../hw/pci/pci.c:255: pci_bus_change_irq_level: Assertion
`irq_num >= 0' failed.
but it was doing that on 5.2 as well.
