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 Change-Id: I837f1a027b836996bc42389bdf7dbab7f0e9db09 Signed-off-by: Uwe Poeche <uwe.poeche@siemens.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/34345 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Werner Zeh <werner.zeh@siemens.com>
