hardware/t100ha: Fix support for SDIO WiFi card
While I had terse Internet connectivity these days, I haven't checked T100HA hardware related news/patchs very often. Meanwhile a small patch by @tagorereddy popped up on hadess/rtl8723bs#80 which works around the SDIO detection. On some devices the BIOS has an option to map the SDIO controller to PCI instead of ACPI, but the T100HA doesn't have this option. IIUC the issue here is that the controller is already being attached via PCI device ID 80862280, which prevented the platform device from being attached via ACPI. The patch circumvents that by removing PCI device ID 80862280 while probing for ACPI devices in SDHCI (yes, very hacky but works) and forces the ACPI platform device to be initialized if the HID is 80860F14:02. I've rebased and tidied up the original patch a bit to prevent warnings during build. Other than this patch, we now need to add the right firmware and the corresponding parameters to hardware.firmware, so that the actual driver for the WiFi card can be loaded. The firmware parameters are stored in EFI on the host itself: /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 So I added a copy of it to prevent impurities.
