hinic3: select CONFIG_DIMLIB

The driver started using dimlib but fails to select the corresponding
symbol, which results in a link failure:

x86_64-linux-ld: drivers/net/ethernet/huawei/hinic3/hinic3_irq.o: in function `hinic3_poll':
hinic3_irq.c:(.text+0x179): undefined reference to `net_dim'
x86_64-linux-ld: drivers/net/ethernet/huawei/hinic3/hinic3_irq.o: in function `hinic3_rx_dim_work':
hinic3_irq.c:(.text+0x1fb): undefined reference to `net_dim_get_rx_moderation'
