Fixes small changes in Makefile(pr #211)

[gtisan]

I didn't know how to change the commit history of pr #211 therefore
I created a new pull request to fix the problem with SDIO.

You can delete old pr #211 or I can do it after review.

It still doesn't work. :) I have CONFIG_PCI=y and CONFIG_USB=y, but CONFIG_MMC=m.

On ArchLinux/Debian ====> CONFIG_MMC=m
On Ubuntu/LinuxMint ====> CONFIG_MMC=y

so ifneq ($(CONFIG_MMC), ) should be better.

Thanks, I did it.

In this repo the firmware for 8822cu(rtw8822c_fw.bin) is older than in linux-firmware.
Is it fine or should we upgrade to the latest firmware ?

[dubhater]

We should upgrade the firmware.

[a5a5aa555oo]

I compared the firmware files here with the ones in linux-firmware, and the result is as below:
rtl8822cu_fw.bin: firmware for bt, older than the one in linux-firmware (0xFFB8_ABD3 vs AED6_6DCB)
rtw8723d_fw.bin: identical
rtw8812a_fw.bin: only exist in this repo
rtw8821a_fw.bin: identical
rtw8821c_fw.bin: older than the one in linux-firmware (v24.8 vs v24.11)
rtw8822b_fw.bin: identical
rtw8822c_fw.bin: older than the one in linux-firmware (v9.9.13 vs v9.9.15)
rtw8822c_wow_fw.bin: identical

I can upgrade them and put all the firmware files in a folder called "firmware" if you permit.

@a5a5aa555oo Sounds good to me. I think we can delete the Bluetooth firmware because this repository doesn't provide Bluetooth drivers.

[a5a5aa555oo]

@dubhater I think so,too. I will delete rtl8822cu_fw.bin and add/upgrade all the firmware needed for rtw88, thank you!~

[dubhater]

Merged, thank you!

@gtisan Does this break the uninstall target? It tries to unload the SDIO modules, which maybe weren't compiled. If the module doesn't exist at all, modprobe -r fails and make aborts.
