crypto: caam - add power management support
Add support for suspend and resume operation for PM in CAAM driver.
When the CAAM goes in suspend, the hardware is considered to do nothing.
On some platforms, the power of the CAAM is not turned off so it keeps
its configuration.
On other platforms, it doesn't so it is necessary to save the state of
the CAAM:
- JRs MID
- Address of input and output rings
