dts: Kconfig: introduce U-Boot list of device tree properties to drop 

Since kernel dtb feature is enabled, U-Boot prop use the same device tree as SPL.
At sometimes there is different require for list of device tree properties to drop
for U-Boot prop, so providing this configure which has higher priority, that if it
is defined empty string, fallback to use OF_SPL_REMOVE_PROPS.
