Remove license notice from STMicroelectronics files

Since a while the source files license info are defined by SPDX
identifiers. We can safely remove the verbose license text from the

Add SPDX license identifiers

Adds one SPDX-License-Identifier line [1] to each source files that

The scancode tool [3] was used to double check the license matching
code in the Python script. All the licenses detected by scancode are
either detected by spdxify.py, or have no SPDX identifier, or are false
matches.

Do not hard code the enumerated 'cache_op' IDs.
Remove unsupported (and unused) WRITE_BUFFER_DRAIN operation.
Deprecate L2CACHE_xxx operation IDs and use the already existing
DCACHE_xxx operation IDs instead.

If there is no outer cache, a cache flush request ends in a cache
