dts: arm: Introduce st/mem.h for FLASH & SRAM sizes
As there can be a large number of FLASH & SRAM sizes for the same SoC having a dts/dtsi for each one would be extremely painful. Lets just use some #defines to set that FLASH & SRAM sizes based on the SoC that is being built. Change-Id: I06388ada4e49ed3d576da31150288512bb6b4485 Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
