From: Tang Yuantian <yuantian.t...@nxp.com>

Commit d97dc8a0 separated the non-command code into its own file
which caused variable sata_curr_device can not be set to a correct
value.

Before commit d97dc8a0, variable sata_curr_device can be set
correctly in sata_initialize().
After commit d97dc8a0, sata_initialize() is moved out to its own file.
Accordingly, sata_curr_device is removed from sata_initialize() too.
This caused sata_curr_device never gets a chance to be set properly
which prevent other command from being executed.

This patch sets variable sata_curr_device properly.
