efi: Correct Macmini DMI match in uefi cert quirk
It turns out Apple doesn't capitalise the "mini" in "Macmini" in DMI, which is inconsistent with other model line names. Correct the capitalisation of Macmini in the quirk for skipping loading platform certs on T2 Macs. Currently users get: ------------[ cut here ]------------ [Firmware Bug]: Page fault caused by firmware at PA: 0xffffa30640054000 WARNING: CPU: 1 PID: 8 at arch/x86/platform/efi/quirks.c:735 efi_crash_gracefully_on_page_fault+0x55/0xe0 Modules linked in: CPU: 1 PID: 8 Comm: kworker/u12:0 Not tainted 5.18.14-arch1-2-t2 #1 4535eb3fc40fd08edab32a509fbf4c9bc52d111e Hardware name: Apple Inc.
