As mentionned in the previous thread,
build_pci_host_bridge_osc_method() is called from gpex-acpi.c whose compilation
depend on
pci_ss.add(when: ['CONFIG_PCI_EXPRESS_GENERIC_BRIDGE', 'CONFIG_ACPI'],
if_true: files('gpex-acpi.c'))
so the hard dependency exists only if ACPI is selected.
If one use "select", ACPI_PCI will be mandated even if ACPI is not set. I am
not sure this is what we want.
"Imply" was supposed to condition the selection depending on ACPI_PCI
dependencies, ie. ACPI and PCI
