Nothing earth-shaking in here, just a lot of refactoring and cleanup and a few bugfixes. I suspect I'll have another pullreq to come in the early part of next week...

It never caused any problems by pure luck: We were not setting class_size for TYPE_ARM_SSE, so class_size of TYPE_SYS_BUS_DEVICE was being used (sizeof(SysBusDeviceClass)). This made the system allocate enough memory for TYPE_ARM_SSE devices even though ARMSSEClass was too small for a sysbus device. Additionally, the ARMSSEClass::info field ended up at the same offset as SysBusDeviceClass::explicit_ofw_unit_address. This would make sysbus_get_fw_dev_path() crash for the device. Luckily, sysbus_get_fw_dev_path() never gets called for TYPE_ARM_SSE devices, because qdev_get_fw_dev_path() is only used by the boot device code, and TYPE_ARM_SSE devices don't appear at the fw_boot_order list.

Then commit 58a26b477e9 ("Emulate a serial bluetooth HCI with H4+ extensions and attach to n8x0's UART") added n8x0_uart_setup() which create the UART and connects it to an IRQ output, overwritting the existing peripheral and its IRQ connection. This is incorrect. Fortunately we don't need to fix this, because commit 6da68df7f9b ("hw/arm/nseries: Replace the bluetooth chardev with a "null" chardev") removed the use of this peripheral. We can simply remove the code.

Connecting two qemu_irqs outputs directly to the same input is not valid as it produces subtly wrong behaviour (for instance if both the IRQ lines are high, and then one goes low, the INTC input will see this as a high-to-low transition even though the second IRQ line should still be holding it high). This kind of wiring needs an explicitly created OR gate; add one.
