ethernet: ti: am65-cpts: Add missing inline qualifier to stub functions

When building with Clang:

In file included from drivers/net/ethernet/ti/am65-cpsw-ethtool.c:15:
drivers/net/ethernet/ti/am65-cpts.h:58:12: warning: unused function

static void am65_cpts_estf_disable(struct am65_cpts *cpts, int idx)
            ^
3 warnings generated.

These functions need to be marked as inline, which adds __maybe_unused,
to avoid these warnings, which is the pattern for stub functions.
