[Qemu-devel] [PATCH for-2.5 1/2] sdhci: Sanitize "sdhci-pci" properties for future qomification

[Markus Armbruster]

We currently fuse controller and card into a single device model, but
we intend qomify things properly and separate the two.  The properties
that really belong to the card would then have to somehow pass-through
to the card's properties.  To avoid that complication, either mark
them experimental or drop them.

Properties "capareg", "maxcurr" and the usual PCI device properties
belong to the controller.  Property "drive" belongs to the card;
rename it to "x-drive".  Properties "logical_block_size",
"physical_block_size", "min_io_size", "opt_io_size",
"discard_granularity" belong to the card, but have no effect; drop
them.
