[PATCH v2] ethernet: qualcomm: QCOM_EMAC should depend on HAS_DMA and HAS_IOMEM

[Geert Uytterhoeven]

If NO_DMA=y:

    drivers/built-in.o: In function `emac_probe':
    emac.c:(.text+0x3780b8): undefined reference to `bad_dma_ops'
    emac.c:(.text+0x3780e2): undefined reference to `bad_dma_ops'
    emac.c:(.text+0x378112): undefined reference to `bad_dma_ops'
    emac.c:(.text+0x378146): undefined reference to `bad_dma_ops'
    emac.c:(.text+0x37816e): undefined reference to `bad_dma_ops'
    drivers/built-in.o:emac.c:(.text+0x37819a): more undefined references to `bad_dma_ops' follow

If NO_IOMEM=y:

    drivers/net/ethernet/qualcomm/emac/emac.c: In function ‘emac_remove’:
    drivers/net/ethernet/qualcomm/emac/emac.c:736:3: error: implicit declaration of function ‘iounmap’ [-Werror=implicit-function-declaration]
       iounmap(adpt->phy.digital);
       ^

Add dependencies on HAS_DMA and HAS_IOMEM to fix this.

Applied.
