637c20e3cf grandcentral: Handle bit-flipping of MAC address. 
If the ENET ROM begins with 0x10, then the bits of each byte are flipped 7..0 -> 0..7 which means the MAC address will begin with 0x08.
A MAC address beginning with 0x08 can be bit-flipped or not bit-flipped.
A MAC address cannot begin with 0x10.
I have a `dump-device-tree` output for a Power Mac 9500 with MAC address beginning with 08-00-07 (OUI for "Apple, Inc."). I don't know if it's using the bit-flipped ROM (starting with 10) or not bit-flipped ROM (starting with 08).
Most of the other `dump-device-tree` outputs I've seen have a MAC address beginning with an OUI for "Apple, Inc." that begins with 00.

4479387580 Remove using namespace std from remaining header files 
It's somewhat of an anti-pattern, and can lead to conflicts with
other symbols (e.g. the Windows build failure in https://github.com/dingusdev/dingusppc/actions/runs/11762906342/job/32766290288,
I removed `using namespace std` from timermanager.h to fix that one).

e7eb1c8a66 Fix PCI interrupts and add devices. 
- Use interrupt source instead of IRQ ID in the IrqMap.
- Add a get_interrupt_controller method to mirror the set_interrupt_controller method.
- Have PCI hosts use pcihost_device_postinit to add PCI devices. This was moved from bandit's device_postinit and allows for duplicate devices by appending the slot to the registered device name.
- Fix interrupts of Pippin.

Fix interrupts of cmd646
- Make it work like other PCI devices.
- IntDetails is built into the pcibase base class.
- IntDetails is initialized by calling pci_interrupt.
- pci_interrupt checks the "enable interrupts" flag before doing an interrupt.

c6116fcc88 grandcentral: pass Curio DREQ state to its DMA channel. 
Bit 5 of the channel status register of the SCSI0 DMA channel
reflects the DREQ signal from Curio.
The old SCSI API still used in some Macintosh applications
- most notably HD SC Setup and Drive Setup - relies on this API
and that signal to be implemented.

64a5a17df0 heathrow: fix interrupt masking. 
Use int_mask1/int_mask2 directly without changing int_events1/int_events2.
That permits interrupt generation on int_mask1/int_mask2 changes.

- Make all IOBusDevices use the same code.
- Log error if 4 least significant bits of offset are not zero.
- Correctly byte swap the value before passing it to the IOBusDevice.
- When reading, duplicate the bytes in a word or dword like a real Power Mac does.
