media: coda: use genalloc API
This patch depends on "genalloc: add devres support, allow to find a managed pool by device", which provides the of_get_named_gen_pool and dev_get_gen_pool functions.

+Chips&Media Coda multi-standard codec IP
+Coda codec IPs are present in i.MX SoCs in various versions,
+called VPU (Video Processing Unit).
+Required properties:
+- compatible : should be "fsl,<chip>-src" for i.MX SoCs:
+ (a) "fsl,imx27-vpu" for CodaDx6 present in i.MX27
+ (b) "fsl,imx53-vpu" for CODA7541 present in i.MX53
+ (c) "fsl,imx6q-vpu" for CODA960 present in i.MX6q
+- reg: should be register base and length as documented in the
+ SoC reference manual
+- interrupts : Should contain the VPU interrupt. For CODA960,
+ a second interrupt is needed for the MJPEG unit.
+- clocks : Should contain the ahb and per clocks, in the order
+ determined by the clock-names property.
+- clock-names : Should be "ahb", "per"
+- iram : phandle pointing to the SRAM device node
+vpu: vpu@63ff4000 {
+ compatible = "fsl,imx53-vpu";
+ reg = <0x63ff4000 0x1000>;
+ interrupts = <9>;
+ clocks = <&clks 63>, <&clks 63>;
