powerpc: Make function that parses RTAS error logs global
The IO event interrupt code has a function that finds specific sections in an RTAS error log. We want to use it in the EPOW code so make it global. Rename things to make it less cryptic: find_xelog_section() -> get_pseries_errorlog() struct pseries_elog_section -> struct pseries_errorlog Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
