fix(fconf): boot fails using ARM_ARCH_MINOR=8

When building TF-A (with SPMD support) with ARM_ARCH_MAJOR=8/
ARCH_ARCH_MINOR=8 options, this forces the -march=armv8.8-a compiler
option. In this condition, the compiler optimises statement [1] into
a store pair to an unaligned address resulting to a supposedly alignment
fault. With -march=armv8.7-a and earlier the compiler resolves with a
memcpy. Replacing this line by an explicit memcpy masks out the issue.
Prefer using the plain struct uuid in place of the uuid_helper union
for further clarity.
