include/spi-generic: move common flash timeouts
This patch moves SPI_FLASH time-outs from spi/spi_flash_internal.h for
SPI SW-sequencing to include/spi-generic.h to provide also for
SPI HW-sequencing.
tested on siemens/bdx1 and checked if all includes of
spi_flash_internal.h on other places provide an include of
spi-generic.h before
