doc: binding: rename directory ram to memory-controller

Alignment with kernel directory name as it have already bindings for
DDR controllers in the directory:
Documentation/devicetree/bindings/memory-controller

PS: the drivers using RAM u-class should be associated with
    this binding directory

-ST, stm32 flexible memory controller Drive
-Required properties:
-- compatible	: "st,stm32-fmc"
-- reg		: fmc controller base address
-- clocks	: fmc controller clock
-u-boot,dm-pre-reloc: flag to initialize memory before relocation.
-
-on-board sdram memory attributes:
-- st,sdram-control : parameters for sdram configuration, in this order:
-  number of columns
-  number of rows
-  memory width
-  number of intenal banks in memory
-  cas latency
-  read burst enable or disable
-  read pipe delay
-
-- st,sdram-timing: timings for sdram, in this order:
-  tmrd
-  txsr
-  tras
-  trc
-  trp
-  trcd
-
-There is device tree include file at :
-include/dt-bindings/memory/stm32-sdram.h to define sdram control and timing
-parameters as MACROS.
-
-Example:
-	fmc: fmc@A0000000 {
-	     compatible = "st,stm32-fmc";
-	     reg = <0xA0000000 0x1000>;
-	     clocks = <&rcc 0 64>;
-	     u-boot,dm-pre-reloc;
-	};
-
-	&fmc {
-		pinctrl-0 = <&fmc_pins>;
-		pinctrl-names = "default";
-		status = "okay";
