[PATCH] ath79: remove num-chipselects from SPI controller

[Adrian Schmutzler]

The num-chipselects property is only valid for bit-banged spi-gpio [1].

For the generic SPI controller bindings, num-cs would be the correct
property [2].

Since the value does not seem to be required anyway, though, let's
just remove it.
