powerpc/powernv: Fix pci-cxl.c build when CONFIG_MODULES=n
pnv_cxl_enable_phb_kernel_api() grabs a reference to the cxl module to prevent it from being unloaded after the PHB has been switched to CX4 mode. This breaks the build when CONFIG_MODULES=n as module_mutex doesn't exist. However, if we don't have modules, we don't need to protect against the case of the cxl module being unloaded. As such, split the relevant code out into a function surrounded with #if IS_MODULE(CXL) so we don't try to compile it if cxl isn't being compiled as a module.
