DW SPI: Get clock value from Device Tree

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) don't use standard clock API
and implement dw_spi_get_clk their own way in their clock manager.

actual boot, but it does not prevent the script located on the SATA
drive from being executed, and thus, both scripts from being mixed up.

configs: am335x_boneblack: Bring back missed bootcmd

Commit b6251db8c3f0 ("Kconfig: Introduce USE_BOOTCOMMAND and migrate
BOOTCOMMAND") removed CONFIG_BOOTCOMMAND option from
include/configs/am335x_evm.h file. But that option wasn't added to
defconfig files for BeagleBone Black board.

Because of this we can't boot Linux from SD card using just
"run bootcmd", getting next error:

    ** File not found /boot/undefined **

That's because "fdtfile" variable has "undefined" value by default, and
"bootcmd" doesn't call "run findfdt" command, which assigns "fdtfile" to
correct device tree file for current board name (obtained from EEPROM).

So we are forced to either call "run findfdt" command manually, or
assign manually "fdtfile=am335x-boneblack.dtb" (e.g. in uEnv.txt file).

Bring back CONFIG_BOOTCOMMAND to BBB defconfigs so that we can boot
Linux rootfs from SD card automatically without any addition actions.
