crypto: inside-secure: improve clock management

Hi,

This short series fixes the way the clocks are used for the SafeXcel EIP-197 controller embedded in the Marvell Armada 7K/8K SoCs. On these SoCs a second one is needed in order to clock the registers. It was not noticed until now because we relied on the bootloader and also because the clock driver was wrong.

Thanks to this fix, it would be possible to fix the clock driver without introducing a regression.

While I was working on the clocks I found a bug in the clock management which was fixed with the first patch and should be applied to v4.16.

The second patch is a small improvement which is aim for v4.17 as well as the last patch.

Thanks,

Gregory
