The global hci_hotkey_quickstart quirk flag is tested in
toshiba_acpi_enable_hotkeys() before the quirk flag is properly
initialized based on SMBIOS data. This causes the quirk to be
applied to all models, some of which behave erratically as a
result.
Fix this by initializing the global quirk flags during module
initialization before registering the ACPI driver. This also
allows us to mark toshiba_dmi_quirks[] as __initconst.
Fixes: 23f1d8b47d12 ("platform/x86: toshiba_acpi: Add quirk for buttons on Z830")
