uboot: add support for new HWID fields to boot scripts 

The new HWID fields make U-Boot create new variable 'module_ram'.

If it exists calculate new HWID fields to check if the SOM has
Wi-Fi, Bluetooth, etc. in order to select the device tree file.
If not, fall back to old method of using the variant code and
the hard-coded table of variants.
