LPC55S69: reinit after power-down mode

Hi !

Looks like after power-down mode  almost all peripherals should be reinitialized.

"

It is the responsibility of the customer application to re-configure all modules in
the power domain core PD_CORE (whose states have not been retained (i.e., SDMA,
PowerQuad, and all Flexcomm products except for Flexcomm3).

"

I reinitialized some flexcomm interfaces but what about peripherals like:

HASHCRYPT and RNG ?

Should they be reinitialized as well after power down ?

Regards,

Eugene
