hv: utils: add PTP_1588_CLOCK to Kconfig to fix build
commit 1dc2f2b81a6a9895da59f3915760f6c0c3074492 upstream.
The hyperv utilities use PTP clock interfaces and should depend a
a kconfig symbol such that they will be built as a loadable module or
builtin so that linker errors do not happen.
Prevents these build errors:
ld: drivers/hv/hv_util.o: in function `hv_timesync_deinit':
hv_util.c:(.text+0x37d): undefined reference to `ptp_clock_unregister'
ld: drivers/hv/hv_util.o: in function `hv_timesync_init':
hv_util.c:(.text+0x738): undefined reference to `ptp_clock_register'
Fixes: 3716a49a81ba ("hv_utils: implement Hyper-V PTP source")
