spi: ingenic: Add support for new Ingenic SoCs.
1.Since it would be dangerous to specify a newer SoC's compatible
string as the fallback of an older SoC's compatible string, we
add support for the "ingenic,jz4775-spi" compatible string in
the driver.
This will permit to support the JZ4775 by having:
compatible = "ingenic,jz4775-spi";
Instead of doing:
compatible = "ingenic,jz4775-spi", "ingenic,jz4780-spi";
2.Add support for probing the spi-ingenic driver on the X1000 SoC
from Ingenic. From the X1000 SoC onwards, the maximum frequency
allowed by the SSI module of Ingenic SoCs has been changed from
54MHz to 50MHz. So "max_speed_hz" is introduced in "jz_soc_info"
to set different maximum frequency values.
3.Add support for probing the spi-ingenic driver on the X2000 SoC
from Ingenic. The X2000 SoC has only one native chip select line,
so "max_native_cs" is introduced in "jz_soc_info" to set different
maximum number of native chip select lines.
4.Because of the introduction of support for the X-series SoCs, the
current driver is not only applicable to the JZ-series SoCs, so
the description texts has been modified to avoid misunderstanding.
