Subject: [PATCH 5.5 016/120] PCI/switchtec: Use dma_set_mask_and_coherent()

From: Wesley Sheng <wesley.sheng@...rochip.com>

commit aa82130a22f77c1aa5794703730304d035a0c1f4 upstream.

Use dma_set_mask_and_coherent() instead of dma_set_coherent_mask() as the
Switchtec hardware fully supports 64bit addressing and we should set both
the streaming and coherent masks the same.

[logang@...tatee.com: reworked commit message]
Fixes: aff614c6339c ("switchtec: Set DMA coherent mask")
