With posix timers having become optional, we get a build error with
the cpts time sync option of the CPSW driver:

drivers/net/ethernet/ti/cpts.c: In function 'cpts_find_ts':
drivers/net/ethernet/ti/cpts.c:291:23: error: implicit declaration of function 'ptp_classify_raw';did you mean 'ptp_classifier_init'? [-Werror=implicit-function-declaration]

It really makes no sense to build this driver if we can't use PTP,
so it's better to go back to 'select PTP_1588_CLOCK' but instead
add a dependency on POSIX_TIMERS.

Fixes: baa73d9e478f ("posix-timers: Make them configurable")
