chip/npcx: Disable linker section check warning
When linking with clang (lld), it complains that the .header and .text
virtual memory address (VMA) overlaps:
ld.lld: error: section .header virtual address range overlaps with .text
>>> .header range is [0x10070000, 0x1007003F]
>>> .text range is [0x10070000, 0x10095DDB]
However, in this case it appears that it's ok that the header overlaps
with the text section, since the bootloader uses the header to copy the
firmware from flash to RAM (the header itself is not copied).
