Yes, I just checked patch#12 "ns16550: move CONFIG_SYS_NS16550 to
Kconfig" (a huge patchset) and found CONFIG_SYS_NS16550 is not on by
default for x86, so this line in efi-x86 can be removed. Previously I
was thinking the option is still on and if that's the case, this line
in efi-x86 should not be removed otherwise efi-x86 won't work.
