wr_vic: moved to wr_minic dir; simplified make

This unifies wr_vic and wr_minic in a single directory,
which results in a simplification of Makefiles.
EXTRA_CFLAGS has been removed as it's now not needed any more.

Makefile

 
-export WR_MODULES_DIR = $(shell /bin/pwd)
-
-DIRS = wr_vic wr_minic
+DIRS = wr_minic
 
 # We may "LINUX ?= /usr/src/linux-wrswitch", but it's better to leave it empty
 

wr_minic/Makefile

 
-obj-m := wr_minic.o
-
-# This is needed to include wr_vic.h
-WR_MODULES_DIR ?= $(shell /bin/pwd)/..
-
-EXTRA_CFLAGS = -I$(WR_MODULES_DIR)/wr_vic
+obj-m := wr_vic.o wr_minic.o
 
 export ARCH ?= arm
 export CROSS_COMPILE ?= $(CROSS_COMPILE_ARM)

wr_vic/Makefile

-
-obj-m := wr_vic.o
-
-export ARCH ?= arm
-export CROSS_COMPILE ?= $(CROSS_COMPILE_ARM)
-
-all modules:
-	$(MAKE) CONFIG_DEBUG_SECTION_MISMATCH=y \
-		-C $(LINUX) SUBDIRS=$(shell /bin/pwd) modules
-
-# We might "$(MAKE) -C $(LINUX)" but "make clean" with no LINUX defined
-# is sometimes useful to have
-clean:
-	rm -f *.mod.c *.o *.ko .*cmd Module.symvers modules.order
-	rm -rf .tmp_versions
