Description:
- Reading configuration register RCPM_IPPDEXPCR1
always return zero
Workaround:
- Save register RCPM_IPPDEXPCR1's value to
register SCFG_SPARECR8.(uboot's psci also
need reading value from the register SCFG_SPARECR8
to set register RCPM_IPPDEXPCR1)
Impact:
- FlexTimer module will cannot wakeup system in
deep sleep on SoC LS1021A

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.
