UPSTREAM: spi: kirkwood_spi: implement workaround for FE-9144572
Erratum NO. FE-9144572: The device SPI interface supports frequencies of
up to 50 MHz. However, due to this erratum, when the device core clock
is 250 MHz and the SPI interfaces is configured for 50MHz SPI clock and
CPOL=CPHA=1 there might occur data corruption on reads from the SPI
device.
Implement the workaround by setting the TMISO_SAMPLE value to 0x2
in the timing1 register.

spi: kirkwood_spi: Add support for multiple chip-selects on MVEBU
Currently only chip-select 0 is supported by the kirkwood SPI driver.
The Armada XP / 38x SoCs also use this driver and support multiple chip
selects. This patch adds support for multiple CS on MVEBU.
The register definitions are restructured a bit with this patch. Grouping
them to the corresponding registers.
