From: Chih-Kang Chang <gary.chang@realtek.com>

For WoWLAN mode, we need to download WoWLAN firmware by calling
fw_download(). Another, to disable/enable WiFi CPU is needed before
calling fw_download. Since Firmware runs on WiFi CPU, it is intuitive
to combine enable_cpu/disable_cpu functions into fw_download.
