The existing code waits a whole second for the AHCI controller to reset.
Instead, let's poll the status register to see if the reset has
succeeded and return earlier if possible. This brings down the time for
AHCI probing from 1s to 20ms.

With an Intel AHCI controller, the driver does not operate properly
if the requested amount of blocks to read exceeds 255.
It is probably possible to specify 0 as the block count and the driver
will read 256 blocks, but it was decided to limit the number of blocks
read at once to 128 (it should be a power of 2 for the optimal
performance of solid state drives).

The code assumes that the pci bus address and the virtual
address used to access a region are the same, but they might
not be. Fix this assumption.
