[PATCH -next] net: mlx5: Kconfig: Fix MLX5_CORE_EN dependencies

From: Mao Wenan
Date: Mon Aug 26 2019 - 23:09:37 EST

When MLX5_CORE_EN=y and PCI_HYPERV_INTERFACE is not set, below errors are found:
drivers/net/ethernet/mellanox/mlx5/core/en_main.o: In function `mlx5e_nic_enable':
en_main.c:(.text+0xb649): undefined reference to `mlx5e_hv_vhca_stats_create'
drivers/net/ethernet/mellanox/mlx5/core/en_main.o: In function `mlx5e_nic_disable':
en_main.c:(.text+0xb8c4): undefined reference to `mlx5e_hv_vhca_stats_destroy'

This because CONFIG_PCI_HYPERV_INTERFACE is newly introduced by 'commit 348dd93e40c1
("PCI: hv: Add a Hyper-V PCI interface driver for software backchannel interface"),
Fix this by making MLX5_CORE_EN imply PCI_HYPERV_INTERFACE.
