The driver is using platform_driver_probe() during initialization,
so ahci_driver.probe hook is never used.
But it causes the following (harmless, luckily) section mismatch:
WARNING: vmlinux.o(.data+0x2fb20): Section mismatch in reference
from the variable ahci_driver to the function .init.text:ahci_probe()
This patch removes the ahci_driver.probe assignment, thus fixes
the warning.
p.s. Note that there's another patch[1] from Rene Bolldorf that
tried to solve the same issue by __refdata annotation. __refdata
says that this reference is actually OK, but in fact it is not OK,
because dereferencing .probe() will cause problems. So the proper
fix is to remove the assignment.

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.

Implicit slab.h inclusion via percpu.h is about to go away. Make sure
gfp.h or slab.h is included as necessary.

This can be used for AHCI-compatible interfaces implemented inside
System-On-Chip solutions, or AHCI devices connected via localbus.
