ar71xx: fix format of the 741-MIPS-ath79-add-PCI-for-QCA9556-SoC patches

The patches introduced in commit 20e68f6d39 ("ar71xx: kernel: enable
PCI on QCA9556 SoC") have non standard format. In unified diff format,
the unchanged, contextual lines must be preceded by a space character.

Refresh the patches with quilt to fix them.
