[PATCH] samples: pfsm: add CC_CAN_LINK dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

When no libc for the target architecture is available, cross-compiling
the same cannot work:

samples/pfsm/pfsm-wakeup.c:12:10: fatal error: fcntl.h: No such file or directory

Fixes: 9e66fb5244953 ("samples: Add userspace example for TI TPS6594 PFSM")
