Merge linker scripts in bootrom to have a single linker script for the bootloader proper (previously known as bootrom-merged.s19)

Browse source 
Remove the now unnecessary files (merge-srec.pl, ldscript-ram-jtag)
Note that this drops the dependency on perl for bootrom build, so end-users who don't touch the FPGA bitstream will not need perl anymore
