crypto: crypto4xx - Perform read/modify/write on device control register
The Security function on the AMCC SoCs has multiple engines within a
single MMIO range. The crypto driver currently enables the 3DES
functionality by doing a blind write to the device control register.
This can unintentionally disable other functions like the PKA or TRNG
when the driver is loaded.
Perform a read/modify/write to enable the 3DES function instead.
