USB: typec: fsusb302: remove unused variables snk_pdo and toggling_mode_name

Variables snk_pdo and toggling_mode_name are defined but are not used and
hence can be removed.

Cleans up clang warnings:
warning: 'snk_pdo' defined but not used [-Wunused-const-variable=]
warning: 'toggling_mode_name' defined but not used [-Wunused-const-variable=]
