Small issue with the BIOS generation

[xy-tech]

Just wanna let you know the commands for generating the new BIOS has a slight mistake in the readme.

dd if=x210-current-internal-flashrom.bin of=fw.bin bs=1024 count=2048 dd if=ec.bin of=fw.bin bs=1024 count=64 seek=2048 dd if=x210-current-internal-flashrom.bin of=fw.bin bs=1024 count=6080 skip=2112 seek=2112

The skip=2112 was missing and if the commands are copy pasted, it'll result in a faulty firmware.
