By using a Kconfig parser we can find the location of each option in the
Kconfig tree. Using the information from the database we can then
automatically add an 'imply' option into the right place if requested by
the user.
Add a -a option to support adding 'imply' options. Display the location of

Sometimes it is useful to display CONFIG_TARGET or CONFIG_CMD configs. Add

It is useful to be able to process only a subset of boards to save time.
Often that subset is defined by the defconfig files in a git commit. This
change allows things like:
# Build the database
./tools.moveconfig.py -b
# Find some implying configs
./tools/moveconfig.py -i CONFIG_X
# Add some 'imply' statements to Kconfig files
./tools/moveconfig.py -i CONFIG_X -a CONFIG_A,CONFIG_B
# Reprocess the defconfig files to see if we can drop some changes
git show --stat | ./tools/moveconfig.py -s -d -
# Update the commit, with fewer defconfig changes
gii commit -au
Where the commit contains defconfig files, this will reprocess them to
take account of the imply statements that you added.

Some AHCI drivers use SCSI under the hood. Rather than making the AHCI
driver be in the SCSI uclass it makes sense to have the AHCI device create
a SCSI device as a child. That way we can handle any AHCI-specific
operations rather than trying to pretend tha the device is just SCSI.
To handle this we need to provide a way for AHCI drivers to bind a SCSI
device as its child, and probe it. Add functions for this.

Two AHCI drivers use SCSI with CONFIG_DM_SCSI. The SCSI uclass calls
scsi_low_level_init() which is implemented by ahci.c. If
CONFIG_SCSI_AHCI_PLAT is defined it does one thing and if it is not
it does something else.
We don't need to call through scsi_low_level_init() to get the init
completed. Instead, adjust the two drivers to call into AHCI directly.
Drop the post-probe init in the SCSI uclass. This means that driver model
doesn't need to use scsi_low_level_init(). It is a legacy function and
driver model should use a driver's probe() method instead.
While we are here, add a comment to the top of the file explaining what
ahci.c does.
