dt-bindings: net: realtek,rtl82xx: Document realtek,*-ssc-enable property

Browse Source 
Document support for spread spectrum clocking (SSC) on RTL8211F(D)(I)-CG,
RTL8211FS(I)(-VS)-CG, RTL8211FG(I)(-VS)-CG PHYs. Introduce DT properties
'realtek,clkout-ssc-enable', 'realtek,rxc-ssc-enable' and
'realtek,sysclk-ssc-enable' which control CLKOUT, RXC and SYSCLK
SSC spread spectrum clocking enablement on these signals. These
clock are not exposed via the clock API, therefore assigned-clock-sscs
property does not apply.
