[PATCH 1/3] hw/sd/sdcard: Deprecate support for spec v1.10

[Philippe Mathieu-Daudé]

We use the v2.00 spec by default since commit 2f0939c234
("sdcard: Add a 'spec_version' property, default to Spec v2.00").
Time to deprecate the v1.10 which doesn't bring much, and
is not tested.

[PATCH 2/3] hw/sd/sdcard: Use spec v3.01 by default

[Philippe Mathieu-Daudé]

Recent SDHCI expect cards to support the v3.01 spec
to negociate lower I/O voltage. Select it by default.
