wifi: mt76: mt7921e: Set memory space enable in PCI_COMMAND if unset

Browse source

commit 09d4d6da1b upstream.

When the BIOS has been configured for Fast Boot, systems with mt7921e
have non-functional wifi.  Turning on Fast boot caused both bus master
enable and memory space enable bits in PCI_COMMAND not to get configured.

The mt7921 driver already sets bus master enable, but explicitly check
and set memory access enable as well to fix this problem.
