Subject: [PATCH v3] clk: socfpga: agilex: add support for the Intel Agilex5

From: Niravkumar L Rabara <niravkumar.l.rabara@intel.com>

Add support for Intel's SoCFPGA Agilex5 platform. The clock manager
driver for the Agilex5 is very similar to the Agilex platform, so
it is reusing most of the Agilex clock driver code.

Changes in v3:
- Used different name for stratix10_clock_data pointer.
- Used a single function call, devm_platform_ioremap_resource().
- Used only .name in clk_parent_data.

Stephen suggested to use .fw_name or .index, But since the changes are on top
of existing driver and current driver code is not using clk_hw and removing
.name and using .fw_name and/or .index resulting in parent clock_rate &
recalc_rate to 0.

In order to use .index, I would need to refactor the common code that is shared
by a few Intel SoCFPGA platforms (S10, Agilex and N5x). So, if using .name for
this patch is acceptable then I will upgrade clk-agilex.c in future submission.

Changes in v2:
- Instead of creating separate clock manager driver, re-use agilex clock
  manager driver and modified it for agilex5 changes to avoid code
  duplicate.
