[PATCH] firmware: xilinx: Remove zynqmp_pm_get_eemi_ops() in IS_REACHABLE(CONFIG_ZYNQMP_FIRMWARE)

[Nobuhiro Iwamatsu]

zynqmp_pm_get_eemi_ops() was removed in commit 4db8180ffe7c: "Firmware: xilinx:
Remove eemi ops for fpga related APIs", but not in IS_REACHABLE(CONFIG_ZYNQMP_FIRMWARE).
This removed zynqmp_pm_get_eemi_ops() in IS_REACHABLE(CONFIG_ZYNQMP_FIRMWARE), and also
modify the documentation for this driver.

Fixes: 4db8180ffe7c ("firmware: xilinx: Remove eemi ops for fpga related APIs")

 EEMI ops is a structure containing all eemi APIs supported by Zynq MPSoC.
 The zynqmp-firmware driver maintain all EEMI APIs in zynqmp_eemi_ops
 structure. Any driver who want to communicate with PMC using EEMI APIs
-can call zynqmp_pm_get_eemi_ops().
-
-Example of EEMI ops::
-
-	/* zynqmp-firmware driver maintain all EEMI APIs */
-	struct zynqmp_eemi_ops {
-		int (*get_api_version)(u32 *version);
-		int (*query_data)(struct zynqmp_pm_query_data qdata, u32 *out);
-	};
-
-	static const struct zynqmp_eemi_ops eemi_ops = {
-		.get_api_version = zynqmp_pm_get_api_version,
-		.query_data = zynqmp_pm_query_data,
-	};
-
-Example of EEMI ops usage::
-
-	static const struct zynqmp_eemi_ops *eemi_ops;
-	u32 ret_payload[PAYLOAD_ARG_CNT];
-	int ret;
-
-	eemi_ops = zynqmp_pm_get_eemi_ops();
-	if (IS_ERR(eemi_ops))
-		return PTR_ERR(eemi_ops);
-
-	ret = eemi_ops->query_data(qdata, ret_payload);
