[U-Boot] [PATCH v5 0/2] DW SPI: Get clock value from Device Tree

[Eugeniy Paltsev]

As discussed with Marek during the LINUX-PITER here is v4 patch:

Add option to set spi controller clock frequency via device tree
using standard clock bindings.

Define dw_spi_get_clk function as 'weak' as some targets
(like SOCFPGA_GEN5 and SOCFPGA_ARRIA10) fon't use standard clock API
and implement dw_spi_get_clk their own way in their clock manager.

Get rid of clock_manager.h include in designware_spi.c as we don't use
cm_get_spi_controller_clk_hz function anymore - we use redefined
dw_spi_get_clk in SOCFPGA clock managers (clock_manager_gen5.c and
clock_manager_arria10.c) instead.

Changes v4->v5:
  * Get rid of usless ifdef in dw_spi_get_clk function
