spl_start_uboot is a board overridable function that switches to falcon
boot mode on return value of 0.

Though for SPI, the falcon boot mode was being enabled on return value
of 1 which is not the correct behaviour. Therefore this patch fixes it
to the expected boot flow.

In boot_from_devices the variable loader is not NULL checked after
assignment and before first use but later code does check it for NULL.
Add a NULL check before first use.

We have a few options that we cannot enable in a "allyesconfig" type
build because we cannot use zero as a default value.

- The logic around HAS_BOARD_SIZE_LIMIT assumes that if we have set this
  then we compare with it. Similarly, we need to set SPL_NO_BSS_LIMIT as
  the default there.
- Both SYS_CUSTOM_LDSCRIPT and ENV_USE_DEFAULT_ENV_TEXT_FILE then prompt
  for a file name to use.
- The SYS_I2C_SOFT driver is a legacy driver which requires a lot of
  configuration within the board config. file instead, so disable it.

Add Renesas R-Car Gen4 SCIF/HSCIF loader compatible SREC generation.
This is a regular U-Boot SPL SREC augmented with a short header which
describes where to store the received data and how much data to store.
This header is interpreted by the R-Car Gen4 BootROM SCIF/HSCIF loader.
