of_find_compatible_node() requires a call to of_node_put() when the
pointer to the node is not required anymore to decrement its refcount
and avoid leaking memory.
Add the missing call to of_node_put() after the node has been used.

Use the devm_platform_ioremap_resource() helper instead of
calling platform_get_resource() and devm_ioremap_resource()
separately

Hardware issue:
- Reading register RCPM_IPPDEXPCR1 always return zero, this causes
system firmware could not get correct information and wrongly do
clock gating for all wakeup source IP during system suspend. Then
those IPs will never get chance to wake system.
Workaround:
- Copy register RCPM_IPPDEXPCR1's setting to register SCFG_SPARECR8
to allow system firmware's psci method read it and do things accordingly.

The NXP's QorIQ processors based on ARM Core have RCPM module
(Run Control and Power Management), which performs system level
tasks associated with power management such as wakeup source control.
Note that this driver will not support PowerPC based QorIQ processors,
and it depends on PM wakeup source framework which provide collect
wake information.
