AM3517 Failed to request pm_wkup irq

When booting the AM3517-EVM, I get a few errors related to the pm.

[    2.038452] pm: Failed to request pm_wkup irq
[    2.042846] omap2_common_pm_late_init: pm soc init failed: -22

omap3_pm_init inside pm34xx.c calls omap_prcm_event_to_irq looking for
"wkup" which returns EINVAL .

Inside omap_prm.c, there are a bunch of data structures for
omap_prm_data which contain for various boards for AM3, AM4, omap4,
omap5 and dra7, but a reference to ti,omap3-prm-inst appears to be
missing.  I looked at the TRM for the AM335X, and i can clearly see a
nice table with addresses that correspond to the tables found in
omap_prm.c, but after looking at both a DM3730 and AM3517 TRM, I am
not seeing a corresponding L4_WKUP Peripheral Memory map.

If someone can point me in the right direction, I can try to setup the
OMAP3 tables accordingly.

thanks
