The downside of using defines in struct ath11k_hw_params.fw.dir is that it's
easy to get it wrong as the full path is not visible. So drop the use of
defines and instead create the patch runtime using a static inline function
ath11k_core_create_firmware_path(). Hopefully this reduces the chances of using
incorrect firmware path.
No functional changes. Compile tested only.
