When SSC work in slave mode, the clock can come from TK pin and also
can come from RK pin, this is hardware design decided. So, make it
available to choose where the clock from.
Changes in v3:
- Move the property from card to ssc device
Series-changes: 2
- using "-" replace "_" in binding document

Add the option to choose clock on which pin input to SSC (as slave).
Default is on TK pin to SSC, add "atmel,clk-from-rk-pin" option to
specify the clock is on RK pin to SSC.
