[PATCH v6 1/3] dt-bindings: mmc: Extend keep-power-in-suspend beyond SDIO

[Kamal Dasu]

keep-power-in-suspend is currently documented as SDIO-only, but the
requirement it describes -- preserving card power across a
suspend/resume cycle -- applies just as well to any card type. Drop
the SDIO-only restriction so eMMC and SD platforms can use it too.

Changes in v6:
  - Split into a separate, minimal patch per Ulf: just extend
    keep-power-in-suspend's scope, with no brcmstb/firmware-specific
    rationale in its description. That rationale now lives in the new
    reset-card-at-resume property instead (patch 2/3), and the two
    are set together on brcmstb rather than folded into one property.
  - Also per Ulf (applies to v4 and v5 alike): dropped the mention of
    sdio_set_host_pm_flags() and how Linux's SDIO stack happens to
    expose this at runtime -- that's a software implementation
    detail, not a hardware/platform description.

Changes in v5:
  - Added Krzysztof's Reviewed-by.

Changes in v4:
  - Dropped no-mmc-poweroff-suspend entirely and extended
    keep-power-in-suspend instead, per Krzysztof: the two properties
    described the same "don't power off across suspend/resume"
    contract.

Changes in v3:
  - Renamed from no-mmc-sleep; dropped S_A_TIMEOUT framing per Ulf.

Changes in v2:
  - New patch, replacing v1's card-level quirk, per Ulf.
