The SCSI uclass currently has no operations. It just uses the global SCSI
functions. Fix this by adding operations to the only two drivers that use
the uclass, and replacing the global functions with those defined locally
in the SCSI code.

With driver model we need to define implementations of exec() and
bus_reset() separately for each SCSI driver. As a first step, create a
local version of each function in the AHCI driver and call each from its
global version.

With driver model these functions need a device pointer. Add one even
when CONFIG_DM_SCSI is not defined. This avoids having ugly conditional

With driver model we cannot have static data or assume that there is only
one device of each time. Adjust the code so that 'probe_ent' is not needed
with driver model. Add a new ahci_init_dm() function which can init AHCI
for driver model without re-allocating the uclass data. Move over the only
existing driver to use this new function.

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.
