[U-Boot] [PATCH RESEND] ahci: dm: Fix memory allocation for uclass private data

[Jean-Jacques Hiblot]

Allocate manually the uclass private data in ahci_init_dm(). Don't do this
in the declaration of the scsi uclass driver with
.per_device_auto_alloc_size because it is AHCI specific.

Since the last merge of u-boot-dm, the DM driver for AHCI on OMAP5 paltforms is
broken. This patche fixes the issue. It had previsouly been sent as part of a
series "dm: ahci: Fix dwc_ahci".
