1.Add SSI nodes for X1000 SoC and X1830 SoC from Ingenic.
2.Refresh SSI related nodes in CU1000-Neo and CU1830-Neo.
3.The X1830 SoC used by the CU1830-Neo and the X1000 SoC
used by the CU1000-Neo are both single-core processors,
therefore the "OST_CLK_PERCPU_TIMER" ABI should not be
used in the OST nodes of the CU1830-Neo and CU1000-Neo,
it is just a coincidence that there is no problem now.
So replace the misused "OST_CLK_PERCPU_TIMER" ABI with
the correct "OST_CLK_EVENT_TIMER" ABI.
