I think it should be src/hal/drivers/mesa-hostmot2. Of course, this
means that the magic auto-compilation of all .comps won't work (that is
only applied in src/hal/components and src/hal/drivers), so for the
moment it's easier to put them directly in src/hal/drivers.

In the case of a .comp file built with comp, it's one source file = one
kernel mdule. In the case of other things it's specified in the
Makefile or something included from the Makefile. For instance,
here's the list of files in hostmot2.ko, in src/Makefile:
hostmot2-objs := \
hal/drivers/mesa-hostmot2/hostmot2.o \
hal/drivers/mesa-hostmot2/backported-strings.o \
hal/drivers/mesa-hostmot2/ioport.o \
hal/drivers/mesa-hostmot2/encoder.o \
hal/drivers/mesa-hostmot2/pwmgen.o \
hal/drivers/mesa-hostmot2/tp_pwmgen.o \
hal/drivers/mesa-hostmot2/sserial.o \
hal/drivers/mesa-hostmot2/mesa_8i20.o \
hal/drivers/mesa-hostmot2/mesa_7i64.o \
hal/drivers/mesa-hostmot2/stepgen.o \
hal/drivers/mesa-hostmot2/watchdog.o \
hal/drivers/mesa-hostmot2/pins.o \
hal/drivers/mesa-hostmot2/led.o \
hal/drivers/mesa-hostmot2/tram.o \
hal/drivers/mesa-hostmot2/raw.o \
hal/drivers/mesa-hostmot2/bitfile.o \
