[PATCH 2/3] phy: brcm-sata: Prepare for doing more tuning

[Florian Fainelli <f.fainelli@gmail.com>]

Split the functional code in brcm_stb_sata_init() to a separate function
that actually does configure spread spectrum: brcm_stb_sata_ssc_init()
and make that function return void, since that function cannot fail.
