[PATCH 1/3] RISC-V: asm: factor relocation related functions into asm/reloc.h

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

To allow use of global_variable_offset() from common PBL code,
move the definition into a new <asm/reloc.h> header.
At current time, it's expected that PBL enabled platforms define
at least get_runtime_offset() there.
