From: Amit Cohen <amcohen@xxxxxxxxxx>
In general, the existing flow of software reset in the driver is:
1. Wait for system ready status.
2. Send MRSR command, to start the reset.
3. Wait for system ready status.
This flow will be extended once a new reset command is supported. As a
preparation, move step #2 to a separate function.
