PATCH 1/1 xtensa: add NOTES section to the linker script

This section collects all source .note.* sections together in the vmlinux image. Without it .note.Linux section may be placed at address 0, while the rest of the kernel is at its normal address, resulting in a huge vmlinux.bin image that may not be linked into the xtensa Image.elf.
