Simplify the DT parsing by removing the parsing of the nvmem layout node
with "st,stm32-nvmem-layout" compatible.

The expected OTP NAME can directly be found in a sub-node named
NAME@ADDRESS of the BSEC node, the NVMEM provider node.

This patch also removes this specific binding introduced for TF-A.

fix(plat/st): improve DDR get size function

Avoid parsing device tree every time when returning
the DDR size.
A cache flush on this size is also added because TZC400 configuration
is applied at the end of BL2 after MMU and data cache being turned off.
Configuration needs to retrieve the DDR size to generate the correct
region. Access to the size fails because the value is still in the data
cache. Flushing the size is mandatory.
