As with all the other undefined values, please use zero.
The driver check is checking for non-zero values which would be true
with USHRT_MAX. You don't happen to see this because of the OMAP1 #ifdef.

Probably should be done in an additional patch, but the cpu_is_44xx()
above could be removed too.
The 44xx TRM recommends using the wkup_status only (not using set/clear
registers) and the same could be done for the other SoCs.
