arm64: rockchip_defconfig: enable CONFIG_SND_SOC_ROCKCHIP_FORCE_SRAM

Browse Source 
This patch depends on iram node and 'rockchip,force-iram' property.

the example on rk3399 to active this feature is as follows:

iram: sram@ff8d0000 {
	compatible = "mmio-sram";
	reg = <0x0 0xff8d0000 0x0 0x20000>; /* 128k */
};

&dmac_bus {
	iram = <&iram>;
	rockchip,force-iram;
};

if the 'rockchip,force-iram' not defined, fallthrough to normal usage.
