log2 of the device block size serves as the shift value used to calculate
the block number to read in file systems when implementing avaiable block
sizes.
It is needed quite often in file systems thus it is pre-calculated and
stored in the block device descriptor.

- block_dev_desc_t says that block_(read|write) take lbaint_t for blkcnt
not ulong.
- We also move the extern of sata_dev_desc into <sata.h>
- Remove now duplicate declarations from driver-specific headers.

We set sata_curr_device to 0 right after returning from init_sata(), so there's
no point in setting it to the last scanned driver at this point.
Note: there are more duplicities with cmd_sata, but those might be required,
as the code seems to reset the entire controller on every scan, ignoring the
requested port number.

Cast first parameter to sata_cpy()
In /drivers/block/ata_piix.h, ata_id_has_lba48(), ata_id_has_lba(),
ata_id_has_dma(), ata_id_u32(), ata_id_u64() are all defined in
include/libata.h which is included in ata.h which is included by all files
which include ata_piix.h (only ata_piix.c) so these definitions are
supurflous to (and conlict with) this in libata.h. Interestingly, my
compiler complains about ata_id_u64 already being defined, but not
ata_id_u32
ata_dump_id() is defined in include/libata.h and should not be static
(maybe should even use ata_dump_id() in libata.c

The curr_device variable really should be namespaced with a "sata_" prefix
since it is only used by the sata code. It also avoids random conflicts
with other pieces of code (like cmd_mmc):
common/libcommon.a(cmd_sata.o):(.data.curr_device+0x0):
multiple definition of `curr_device'
common/libcommon.a(cmd_mmc.o):(.data.curr_device+0x0): first defined here

original ata_piix driver is using IDE framework, not real
SATA framework. For now, the ata_piix driver is only used
by x86 sc520_cdp board. This patch makes the ata_piix driver
use the new SATA framework, so
- remove the duplicated command stuff
- remove the CONFIG_CMD_IDE define in the sc520_cdp.h
- add the CONFIG_CMD_SATA define to sc520_cdp.h

move the cmd_sata.c from common/ to drivers/ata_piix.c,
the cmd_sata.c have some part of ata_piix controller drivers.
consolidate the driver to have better framework.
