[POWERPC] pseries: Eliminate global error_log_cnt variable 

Eliminate the use of error_log_cnt as a global var shared across
different directories.  Pass it as a parameter instead.

Signed-off-by: Linas Vepstas <linas@austin.ibm.com>

----

Respin of earlier patch, with the CONFIG_PSERIES junk removed from the
header file.
