ldscripts: remove linker script for Raspberry Pi

This linker script was introduced in commit 5426ff9 in 2012
predating both the EFI and the raw u-boot ARM loader,
at that time it seems that it was intended to be used
as part of a 'raspberrypi_arm' boot platform which does
not exist anymore. So this is not needed anymore.
