memory: add Renesas RPC-IF driver
Add the memory driver for Renesas RPC-IF which registers either SPI or
HyperFLash device depending on the contents of the device tree subnode.
It also provides the absract "back end" device APIs that can be used by
the "front end" SPI/MTD drivers to talk to the real hardware.

Based on the original patch by Mason Yang <masonccyang@mxic.com.tw>.

5ec47cda74 memory: move jedec_ddr.h from include/memory to drivers/memory/
Now that jedec_ddr_data.c was moved from lib/ to drivers/memory/,
<memory/jedec_ddr.h> is included only from drivers/memory/.

Make it a local header of drivers/memory/.

The directory include/memory is now gone.

While I am here, I also changed #include <linux/module.h> to
<linux/export.h>. Because CONFIG_DDR is bool, jedec_ddr_data.c is
never compiled as a module.

9c1c21a053 ddr: add LPDDR2 data from JESD209-2
add LPDDR2 data from the JEDEC spec JESD209-2. The data
includes:

1. Addressing information for LPDDR2 memories of different
   densities and types(S2/S4)
2. AC timing data.

This data will useful for memory controller device drivers.
Right now this is used by the TI EMIF SDRAM controller
driver.
