Subject: [PATCH v2 4/4] dt-bindings: mmc: convert sdhci-dove to JSON schema

Convert the sdhci-dove binding to JSON schema. The optional clocks
property was not in the original binding document but has been in the
dove.dtsi since commit 5b03df9ace68 ("ARM: dove: switch to DT clock
providers").

Signed-off-by: Chris Packham <chris.packham@...iedtelesis.co.nz>

    - Add clocks property
    - interrupts.maxItems = 2
    - Update maintainers based on ./scripts/get_maintainer.pl -f drivers/mmc/host/sdhci-dove.c
