[PATCH 1/2] OvmfPkg/Tcg2ConfigPei: trivial coding style updates

[Laszlo Ersek <lersek@redhat.com>]

- the @file comment block should match between INF and main C file

- rewrap / refill columns to 79 characters

- insert space before opening paren

- prefix and suffix //-style comment block with empty // lines

- fix indentation of arguments in multi-line function call

- general tab spacing (indent step) is 2 in edk2, unlike QEMU's 4

No functional changes.
