Subject: ACPI: APD: Change name from ST to FCH
Patch-mainline: v5.9-rc1
Git-commit: d58669b093997e4e5f98c38a54f99761657c19d2
References: jsc#SLE-16407

AMD SoC general pupose clk is present in new platforms with
same MMIO mappings. We can reuse the same clk handler support
for other platforms. Hence, changing name from ST(SoC) to FCH(IP)
