Various fixes and improvements of designware spi driver.
Eugeniy Paltsev (5):
DW SPI: fix tx data loss on FIFO flush
DW SPI: fix transmit only mode
DW SPI: refactor poll_transfer functions
DW SPI: add option to use external gpio for chip select
DW SPI: use 32 bit access instead of 16
we return with error.
Fix that by using SPI_TMOD_TR instead of SPI_TMOD_TO which allows to use
RX FIFO.

. After that we can get rid
of dw_reader return value check in poll_transfer function.
With these changes we're getting closer to Linux DW SPI driver.

Move icache entire operation to separate function as we are planing
to use it in another places (like sync_icache_dcache_all)

K points to invalidate_dcache_all, we call it again and
// loop forever.
Fortunately we may do flush and invalidation of D$ with a single one
instruction which automatically mitigates a situation described above.
And because invalidate_dcache_all isn't used in common u-boot code we

As of today __dc_line_op and __dc_entire_op support
only flush (OP_FLUSH) and invalidate (OP_INV) operations.
Add support of flush and invalidate (OP_FLUSH_N_INV)
operation which we planing to use in next patches.

Move IOC initialization to separate function from cache_init
function.
This is the preparation for the next patch when we will switch
to is_isa_arcv2() function using instead of "CONFIG_ISA_ARCV2"
ifdef using.
Also it makes cache_init function clear.
