The cortex-m52 CPU definition in GCC is updated to remove the quirk_vlldm feature bit. This change reflects that the Cortex-M52 processor does not have the VLLDM erratum associated with CVE-2021-35465, meaning the -mfix-cmse-cve-2021-35465 flag will no longer be enabled by default. Additionally, a typo in the documentation for the CVE number has been corrected.
