clk: spear: Fix SSP clock definition on SPEAr600

There is no SPEAr600 device named "ssp-pl022.x". Instead, the description
of the SSP (Synchronous Serial Port) was recently added to the Device Tree,
and the device name is "xxx.spi", so we should associate the SSP gateable
clock to these device names.
