Base on U-Boot next-dev commit:
(abe2842 tools: rockchip: boot_merger: add option to enable rc4 flag)

The legacy chips like rk3188 maskrom require all IDB data with RC4,
the boot_merger pack the loader with a rc4 flag in header,
and the upgrade_tool will write the data with rc4 to IDB area.

usage:
boot_merger --rc4 RKBOOT/RK310BMINIALL.ini

and you can see log below if success with RC4:
* enable RC4 for IDB data(both ddr and preloader)

Test on rk3188.
