This reverts commit b5eddee5f6.
Using pci function 0 works on my Lenovo P50 but not my Lenovo X1. Don't break
machines where we are shipping the chip rather than ones where we probably are
not, especially when it's probably a kernel bug somewhere.
Fixes https://github.com/fwupd/fwupd/issues/2608
Although hotpluggging PCIe cards isn't common, it's how I'm testing this in the
device test enclosure. Add a tiny delay to wait for the kernel to populate the
net class on hotplug.
- Use pci function 0 instead of 1 when flashing firmware.
In certain situations, the BCM5719 NVM controller can lockup if
a function other than 0 is used to read from NVM word-by-word like
the kernel driver does.
- Fix APE_MODE offset in BAR[2] to enable proper resetting of the APE.
- Remove unnededed NVRam lock when resetting the APE.
