I believe the problem is in patch 4/7

config HISILICON_LPC
	bool "Support for ISA I/O space on Hisilicon Hip0X"
	depends on (ARM64 && ARCH_HISI) || COMPILE_TEST
                                         ^^^^^^^^^^^^

the COMPILE_TEST above allowing HISILICON_LPC also for other architectures. 
I think we can remove "|| COMPILE_TEST"...I will fix it in v10

Gab

+	select LOGIC_PIO
+	select INDIRECT_PIO
+	help
+	  Driver needed for some legacy ISA devices attached to Low-Pin-Count
+	  on Hisilicon Hip0X SoC.
