We're adding support for something new? Only set .fw_name in that case, as
.name will never be used. To do even better, set only .index so that we don't do
any string comparisons.
Yes we are adding Agilex5 SoCFPGA platform specific clocks.
I will remove .name and only keep .fw_name in next version of this patch.

Maybe call this stratix_data so that clk_data.clk_data is stratix_data.clk_data.
Will fix this in next version.

This is a single function call, devm_platform_ioremap_resource().i
Noted. Will fix in next version.
When you resend a V3, just send this patch. I've already applied the
other 4 patches.
