Fix type of cot_desc_ptr
The chain of trust description and the pointer pointing to its first
element were incompatible, thus requiring an explicit type cast for
the assignment.
- cot_desc was an array of
const pointers to const image descriptors.
- cot_desc_ptr was a const pointer to
(non-constant) pointers to const image descriptors.
Thus, trying to assign cot_desc to cot_desc_ptr (with no cast) would
generate the following compiler warning:
drivers/auth/tbbr/tbbr_cot.c:826:14: warning: initialization discards
‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
REGISTER_COT(cot_desc);
