soc/intel/skylake/acpi.c: Name devices on secondary bus
Naming a device allows an ACPI _ROM method to be written for it. GPUs
may require this to make the configuration data contained within
available to an OS driver. This may be required for GPUs that do not
contain their vBIOS, or perhaps the drivers require it in this form/fashion.
Working on an Acer Aspire VN7-572G (Skylake-U). nouveau successfully
obtains the vBIOS via ACPI (kernel 5.7.11).

mb/google/zork: Switch to normal read mode for EM100
This change sets the EFS config for SPI read mode to normal read mode
when using em100. With this, the boot is stable again without any
random hangs in PSP.
