Subject: [PATCH] phy: miphy365x: Fix off-by-one error

We index the RX/TX speed select values in the following way:

  rx_tx_spd[miphy_phy->sata_gen];

However rx_tx_spd[] starts at index zero and the SATA_GENx's start
at one.  In this patch we pad out the first element in rx_tx_spd[]
in an attempt to realign the values.
