firmware: xilinx: Remove zynqmp_pm_get_eemi_ops() in IS_REACHABLE(CONFIG_ZYNQMP_FIRMWARE)

[ Upstream commit 79bfe480a0a0b259ab9fddcd2fe52c03542b1196 ]

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).
Any driver who want to communicate with PMC using EEMI APIs use the functions provided
for each function
This removed zynqmp_pm_get_eemi_ops() in IS_REACHABLE(CONFIG_ZYNQMP_FIRMWARE), and also
modify the documentation for this driver.

-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);
+Any driver who wants to communicate with PMC using EEMI APIs use the
