This is useful to check mocs configuration. Tests/Tools can use
this debugfs entry to get mocs info.

v2: Address review comments. Change debugfs output style similar
to pat debugfs. (Lucas De Marchi)

v3: rebase.

v4: Address review comments. Use function pointer inside ops
struct. Update Test-with links. Remove usage of flags wherever
not required. (Lucas De Marchi)

v5: Address review comments. Move register defines. Modify mocs
info struct to avoid holes. (Luca De Marchi)
