wifi: iwlwifi: mvm: add dependency for PTP clock

When the code to use the PTP HW clock was added, it didn't update
the Kconfig entry for the PTP dependency, leading to build errors,
so update the Kconfig entry to depend on PTP_1588_CLOCK_OPTIONAL.

aarch64-linux-ld: drivers/net/wireless/intel/iwlwifi/mvm/ptp.o: in function `iwl_mvm_ptp_init':
