Several block device properties related to blocksize configuration must
be in certain relationship WRT each other: physical block must be no
smaller than logical block; min_io_size, opt_io_size, and
discard_granularity must be a multiple of a logical block.
To ensure these requirements are met, add corresponding consistency
checks to blkconf_blocksizes, adjusting its signature to communicate
possible error to the caller. Also remove the now redundant consistency
checks from the specific devices.

v5 -> v6:
- fix forgotten xen-block and swim
v4 -> v5:
- fix/reword error messages [Philippe, Kevin]
- do early return on failed consistency check [Philippe]
- use QEMU_IS_ALIGNED instead of open coding [Philippe]

Several BlockConf properties represent respective sizes in bytes so it
makes sense to accept size suffixes for them.
Turn them all into uint32_t and use size-suffix-capable setters/getters
on them; introduce DEFINE_PROP_SIZE32 and adjust DEFINE_PROP_BLOCKSIZE
for that. (Making them uint64_t and reusing DEFINE_PROP_SIZE isn't
justified because guests expect at most 32bit values.)
Also, since min_io_size is exposed to the guest by scsi and virtio-blk
devices as an uint16_t in units of logical blocks, introduce an
additional check in blkconf_blocksizes to prevent its silent truncation.

v5 -> v6:
- add prop_size32 instead of going with 64bit
v4 -> v5:
- make all BlockConf size props support suffixes
- move qdev_prop_blocksize after qdev_prop_size, to reuse get_size
- reword error messages [Kevin]
