mtd: docg3: use devm_platform_ioremap_resource()

Replace the open-coded platform_get_resource(IORESOURCE_MEM, 0) plus
devm_ioremap() sequence with devm_platform_ioremap_resource(), which folds
the resource lookup, region reservation and mapping into one step and
returns an ERR_PTR checked with IS_ERR()/PTR_ERR().

The canonical docg3 register window is DOC_IOSPACE_SIZE (0x2000), which is
the size any platform provides for this device, so mapping the full
resource is equivalent to the previous fixed-size devm_ioremap().

Built for ARM (multi_v7_defconfig + CONFIG_MTD_DOCG3) with LLVM=1;
drivers/mtd/devices/docg3.o compiles cleanly.
