Subject: [PATCH v2 1/6] RISC-V: Move __start_kernel to .head.text

Currently, __start_kernel is kept in _init while _start is in head section.
This may result in "relocation truncated to fit error" if _init section is
moved far from head. It also makes sense to keep entire head.S in one
section.

Keep __start_kernel in head section rather than _init.
