Convert CONFIG_USE_PREBOOT and CONFIG_PREBOOT to Kconfig
This converts the following to Kconfig:
CONFIG_USE_PREBOOT
CONFIG_PREBOOT
Both are together in one commit, since otherwise the former causes kconfig
to define the latter, which gives duplicate symbol errors.
Includes a manual fixup for CONFIG_PREBOOT in ids8313_defconfig since the
backslash lands in the wrong place. Similarly with socfpga_vining_fpga.
