ahci_platform: Provide for vendor specific init

Some AHCI implementations may use Vendor Specific HBA[A0h, FFh]
and/or Port[70h, 7Fh] registers to 'prepare' for initialization.
For that, the platform needs memory mapped address of AHCI registers.

This patch adds the 'mmio' argument and reorders the call to
platform init function.
