This small series upports a BSP improvement in a refactored way. The
original patch 15d7abbfc3f0 ("mmc: renesas_sdhi: reset calibration register")
added a new quirk for devices which always should disable HS400
adjustment. This was only applicable for SoCs which either had bad_taps
or needed a calibration table. So, I simply used this logic directly.
This is patch 2.

To achieve this in a readable way, I finally did something I wanted to
do for some time now. Having a helper to check for SDHI quirks. This is
patch 1.

The series has been tested on a Salvator-XS (R-Car M3-N). The patches
are based on mmc/next as of today as they depend on d901e2ba566 ("mmc:
renesas_sdhi: take DMA end interrupts into account").

Let me know what you think!

Happy hacking,

   Wolfram

Please discard this series. I want to upport another BSP fix, but I need
all patches in a specific order to ease backporting. I'll send a new
series on Monday latest.
