This looks spurious to iounmap resources in the normal path of this init
function.
The 3 ioremap'ed fields of 'pm_config' can be accessed later on in other
functions, so it is likely that we should return 'success' before unrolling
everything.
Fixes: aa9aa1ec2df6 ("ARM: davinci: PM: rework init, remove platform device")

This patch is just a *guess*. The end of the function looks more like a
error handling code rather than a normal path.
