powerpc/rtas: clean up rtas_error_log_max initialization
The code in rtas_get_error_log_max() doesn't cause problems in
practice, but there are no measures to ensure that the lazy
initialization of the static rtas_error_log_max variable is atomic,
and it's not worth adding them.
Initialize the static rtas_error_log_max variable at boot when we're
single-threaded instead of lazily on first use. Use the more
appropriate of_property_read_u32() API instead of rtas_token() to
consult the "rtas-error-log-max" property, which is not the name of an
RTAS function. Convert use of printk() to pr_warn() and distinguish
the possible error cases.
