[ARM] Ensure head text is always placed at the start of kernel
Commit 86c0baf123e474b6eb404798926ecf62b426bf3a highlighted that we
may end up with the head text placed elsewhere in the kernel image.
Introduce a new .text.head section to contain the initial kernel
startup code, and always place this section at the beginning of the
kernel image.
