When blk_create_device() is called some parameters in blk_desc are
automatically filled. Separate SCSI private initialization and SCSI full
block device initialization not to rewrite already prepared data.

With DM_SCSI this function will return more than one return value to
cover errors.

Several functions should be static because they are not exported to any
other file.
Warnings were reported by sparse C=1.

These functions are not called for any location.
This patch removes them scsi_trim_trail(), scsi_get_disk_count()
and scsi_setup_read6().

There is no reason to directly point to static allocated array
when we have proper block_dev pointer available via parameter
in !CONFIG_BLK. For CONFIG_BLK this is read directly from uclass
platdata.

pccb is pointer to temporary buffer which is used only for sending
command. Make it local as is done in scsi_read/scsi_write.

At present the SCSI command code includes both the command-processing code
and the core SCSI functions and data structures.
Separate the latter into its own file, adding functions as needed to avoid
the command code accessing data structures directly. This functions use the
new legacy block functions.
With this commit:
- There is no CONFIG option referenced from the command code
- The concept of a 'current SCSI device' is confined to the command code
This will make it easier to convert this code to driver model.
