--------------------------------------

Disabling CONFIG_ARCH_PHYTIUM results in following compile errors:

drivers/iommu/arm-smmu.c: In function ‘phytium_smmu_def_domain_type’: drivers/iommu/arm-smmu.c:1641:6: error: implicit declaration of function ‘typeof_ft2000plus’ [-Werror=implicit-function-declaration] 1641 | if (typeof_ft2000plus() || typeof_s2500()) { | ^~~~~~~~~~~~~~~~~ drivers/iommu/arm-smmu.c:1641:29: error: implicit declaration of function ‘typeof_s2500’ [-Werror=implicit-function-declaration] 1641 | if (typeof_ft2000plus() || typeof_s2500()) { | ^~~~~~~~~~~~ cc1: some warnings being treated as errors

Fix it by using CONFIG_ARCH_PHYTIUM to control phytium related code.
