Subject: [PATCH] net: broadcom: Add PTP_1588_CLOCK_OPTIONAL dependency for BCMGENET under ARCH_BCM2835

commit 8d820bc9d12b ("net: broadcom: Fix BCMGENET Kconfig") fixes the build
that contain 99addbe31f55 ("net: broadcom: Select BROADCOM_PHY for BCMGENET")
and enable BCMGENET=y but PTP_1588_CLOCK_OPTIONAL=m, which otherwise
leads to a link failure. However this may trigger a runtime failure.

Fix the original issue by propagating the PTP_1588_CLOCK_OPTIONAL dependency
of BROADCOM_PHY down to BCMGENET.

Fixes: 99addbe31f55 ("net: broadcom: Select BROADCOM_PHY for BCMGENET")
