SCSI device scan code was executing TEST UNIT READY command without
explicitly setting dma direction in struct scsi_cmd to NONE, so command
was passed to driver with dma direction set to DMA_FROM_DEVICE,
inherited from older usage.

With WDC SDINDDH6-64G ufs device, that caused TEST UNIT READY to
return error.

Fix that, by explicitly setting dma direction to NONE for
TEST UNIT READY, and restoring it back DMA_FROM_DEVICE for the
following READ CAPACITY.

When we do not have CONFIG_BOUNCE_BUFFER enabled, inside of
scsi_init_dev_desc_priv we never set the 'bb' field to false, we only
initialize it to true when CONFIG_BOUNCE_BUFFER is set. Given that we
have a number of other fields here we had been explicitly setting to
zero, change to first calling memset to clear the struct and then
initialize only the fields that need non-zero default values.

Currently bounce buffer support is enabled for all block devices
when available. Add a flag to blk_desc to enable only on demand.

Some devices have limited DMA capabilities and require that the
buffers passed to them fit specific properties. Add new optional
callback which can be used at driver level to indicate whether a
buffer alignment is suitable for the device DMA or not. This is
a pass-through callback from block uclass to drivers.

make sure it is cache aligned.

This name is a little confusing since it suggests that it sets up the
sibling block device. In fact it sets up a bootdev for it. Rename the
function to make this clearer.

It seems better to call this a 'bootdev' since this is name used in the
documentation. The older 'Bootdevice' name is no-longer used and may cause
confusion with the 'bootdevice' environment variable.

Update throughout to use bootdev.

We need extensions to be set up before we start trying to boot any of the
bootdevs. Add a new priority before all the others for tht sort of thing.
Also add a 'none' option, so that the first one is not 0.

While we are here, comment enum bootdev_prio_t fully and expand the test
for the 'bootdev hunt' command.
