Build issues with ipxe.efi for arm64 architecture

[NiKiZe]

ARM builds does not yet support direct I/O or port calls which makes ipxe.efi invalid for ARM builds since it pulls in drivers which needs this.

Instead of ipxe.efi build the it with the specific driver, or combination of them, for example in your case

Code:

make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 bin-arm64-efi/intel--snp.efi -j8

or whichever driver it is you need
