Subject: [PATCH 1/8] wifi: rtw89: fw: move polling function of firmware path ready to an individual function

To download firmware, we need to check path is ready. There are two kinds
of path -- one is to download firmware header, and the other is to download
firmware body.

Since the polling method is different from WiFi 7 chips, make it to be
an individual function, and then we can reuse the download flow.
