Add a new defconfig based on existing helios4_config file to support booting from spi flash.
Settings for environment location are based on vendor u-boot: https://github.com/kobol-io/u-boot/blob/helios4/include/configs/helios4.h#L5...
A separate defconfig is required because the options are not intuitive from menuconfig, numeric values in particular.

So, a super new thing that might be of interest, but please try this since I'd like to prove/disprove the use-case. This could instead be: configs/helios4_spi_defconfig: #include "configs/helios4_defconfig" ... enable/disable options specific to the SPI boot use case ...
And so now both boards will otherwise be kept in-sync for general config changes. It could further be done as: configs/helios4_spi_defconfig: #include "configs/helios4_defconfig" #include "board/kobol/helios4/spiboot.config"
And have board/kobol/helios4/spiboot.config contain the SPI-boot specific options. This path would allow for: make helios4_defconfig spiboot.config to be a valid alternative way of configuring a build for spiboot.
