powerpc/83xx: gianfar_ptp: select 1588 clock source through dts file
Currently IEEE 1588 timer reference clock source is determined through
hard-coded value in gianfar_ptp driver. This patch allows to select ptp
clock source by means of device tree file node.
For instance:
fsl,cksel = <0>;
for using external (TSEC_TMR_CLK input) high precision timer
reference clock.
Other acceptable values:
<1> : eTSEC system clock
<2> : eTSEC1 transmit clock
<3> : RTC clock input
When this attribute isn't used, eTSEC system clock will serve as
IEEE 1588 timer reference clock.
