Function declarations in headers do not need to come with extern
keyword. Remove them to make the declaration slightly shorter.

Add AC timings information needed to support LPDDR3 and memory
controllers along with helpers to obtain it. These will be necessary
for upcoming Exynos5422 Dynamic Memory Controller driver.

Commit e6b42eb "memory: emif: add device tree support to emif driver"
added drivers/memory/of_memory.c, which references tables defined in
lib/jedec_ddr_data.c. of_memory.c is compiled when CONFIG_OF, whereas
jedec_ddr_data.c is compiled when CONFIG_DDR. This breaks the build
when CONFIG_OF is defined but not CONFIG_DDR:
drivers/built-in.o: In function `of_get_ddr_timings':
drivers/memory/of_memory.c:138: undefined reference to `lpddr2_jedec_timings'
drivers/built-in.o: In function `of_get_min_tck':
drivers/memory/of_memory.c:62: undefined reference to `lpddr2_jedec_min_tck'
make: *** [vmlinux] Error 1
To solve this, only compile of_memory.c when CONFIG_OF && CONFIG_DDR,
otherwise, stub out the functions.

Device tree support for the EMIF driver. LPDDR2 generic timings
extraction from device is managed using couple of helper
functions which can be used by other memory controller
drivers.
