dt-bindings: phy: Add RX equalizer properties for Broadcom SATA PHY 

Define two new properties: brcm,rx-aeq-mode which allows configuring the
SATA PHY RX equalizers and when "manual" is used, brcm,rx-aeq can be
used to set the exact value.

@ -27,7 +27,16 @@ Sub-nodes optional properties:
This property is not applicable for "brcm,iproc-ns2-sata-phy",
"brcm,iproc-nsp-sata-phy" and "brcm,iproc-sr-sata-phy".
Example:
- brcm,rxaeq-mode: string that indicates the desired RX equalizer
mode, possible values are:
"off" (equivalent to not specifying the property)
"auto"
"manual" (brcm,rxaeq-value is used in that case)
- brcm,rxaeq-value: when 'rxaeq-mode' is set to "manual", provides the RX
equalizer value that should be used. Allowed range is 0..63.
Example
sata-phy@f0458100 {
compatible = "brcm,bcm7445-sata-phy", "brcm,phy-sata3";
reg = <0xf0458100 0x1e00>, <0xf045804c 0x10>;
