MdeModulePkg/AtaAtapiPassThru: Spin up Power up in Standby devices

The patch adds support to certain devices that support PUIS (Power
up in Standby).
For those devices that supports SET_FEATURE spin up, SW needs to
send SET_FEATURE subcommand to spin up the devices.
For those devices that doesn't support SET_FEATURE spin up, SW needs
to send read sectors command to spin up the devices.
