This patch reimplement ata_hpa_resize() such that...
* All HPA related decisions are made inside ata_hpa_resize() proper.
ata_hpa_resize() returns 0 if configuration can proceed, -errno if
device needs to be reset and reconfigured.
* All errors are handled properly. If HPA unlocking isn't requested,
HPA handling is disabled automatically to avoid unnecessary device
detection failure.
* Messages are trimmed. HPA detection message is printed only during
initial configuration. HPA unlocked message is printed only during
initial configuration or unlocking results in different size.
* Instead of using sectors returned in TF of SET_MAX, re-read IDENTIFY
data as that's the value the device is going to use.
* It's called early during ata_dev_configure() as IDENTIFY data might
change after resizing.
