arm: Have the linker garbage-collect unused functions and variables
This patch activates -ffunction-sections and -fdata-sections for the
compiler and --gc-sections for the linker. This will strip out all
unused functions and static/global variables from the final binaries and
reduce the amount of data we need to read over SPI.
A quick test with ToT images shows a 2.5k (13%) / 10k (29%) / 12k (28%)
reduction on Nyan and 3k (38%) / 23k (50%) / 13k (29%) on Pit,
respectively for bootblock / romstage / ramstage.
