3e807d6686 dart: shutdown to bypass mode 
This allows payloads to use DMA for anything that's not PCIe
even without a DART driver. It also restores the DART registers
the state the were left by iBoot.

d61bf13cb0 hv: shadow perf monitor IRQ mode and state 
The development Mac OS kernel panics if the PMCR0 sysreg is in an
unexpected state. To avoid that the hypervisor needs to shadow the
interrupt mode and interrupt active flag after it mask the PM FIQ.
Mac OS reads and writes frequently from PMCR0 and PMC 0/1 so handling
in m1n1 is preferred over Python.

9529ec2b4f usb: add hpm_init and split usb_init and usb_iodev_init 
This allows to bringup the USB PHY and the HPM for the
payload without having to initialize the CDC ACM driver
at the same time.

3d1747466b Add an option to disable checksumming if possible 
* Introduce feature flags which allows the proxy and m1n1 to determine which
features they have in common.
* Add a feature flag that disables checksumming (by replacing checksums with
constant values) for the data packets exchanged by REQ_MEMREAD, REQ_MEMWRITE
and REQ_EVENT. The feature is enabled if m1n1 supports it; checksumming is kept
enabled for UART communication.
* To ensure no packet loss when checksumming is disabled, an extra sentinel
value is added after the exchanged data for memory read/write operations.
