amd/gardenia: Update xHCI configuration

Remove a duplicated check and setting for xHCI during the
    AMD_INIT_RESET callout.  This is handled by the wrapper.  Also
    remove nearby commented code.  EcChannel0 is not a member of
    FCH_RESET_DATA_BLOCK.

Leave the check in AMD_INIT_ENV.  Although AGESA honors what
    was previously requested, additional settings depend on the
    state of Usb.Xhci0Enable.
