e88b2fe8b9The CONFIG_AUTOFDO_CLANG option currently depends on ARCH_SUPPORTS_AUTOFDO_CLANG, but this dependency seems unnecessary. Remove ARCH_SUPPORTS_AUTOFDO_CLANG and allow users to control AutoFDO builds solely through CONFIG_AUTOFDO_CLANG. This simplifies the kconfig and avoids potential confusion. Expand the AutoFDO documentation to include instructions for arm64.
