Datasheets describe the used command as 'I2C Read' but adding the
word 'eeprom' in between should avoid further confusion with other
block commands.
Followups will add a symmetrical pair of commands i2c_block_read()
and i2c_block_write() that operate via I2C_EN bit and have a 32
byte size restriction on block transfers. For some hardware revision
these block commands are available, while 'I2C Read' was not.

In these cases we have to expect a NULL pointer because the IGD

The behaviour still differs from using dev_find_slot(), which may
return a disabled device. Though, if you'd try to read its config
space you'd only read garbage (0xff) and in cases where we filled
ACPI data with devicetree information, the information shouldn't
be interpreted by the OS because of the disabled device.

The H81 chipset is the only non-LP Lynx Point chipset with 6 PCIe root
ports, all others have 8 [1]. The existing PCIe code assumed that all
non-LP chipsets had 8 root ports, which meant that port 6 would not be
considered the last root port on H81, so `root_port_commit_config()`
would not run. Ultimately, while PCIe still worked on H81, all the root
ports would remain enabled, even if disabled in the devicetree.
Also, remove `PCI_DEVICE_ID_INTEL_LYNXPOINT_MOB_DESK_{MIN,MAX}`, as they
are unused, and the MAX constant is incorrect.
Interestingly, this fixes an issue where GRUB is unable to halt the
