am33x-cm3: Enforce correct -march option
Buildroot uses a normal ARM compiler to build the AM33X CM3 firmware
(which runs on a Cortex-M3 processor), but Buildroot will have a
default -march value that doesn't necessarily match the one needed for
Cortex-M3, leading to build failures (gcc complains that the
-mcpu=cortex-m3 option being passed is not compatible with the
selected -march).
Fix this by explicitly indicating -march=armv7-m.
