This patch series fixes regression introduced in commit 366697018c9a
("PCI: aardvark: Add PHY support") which caused aardvark driver
initialization failure on EspressoBin board with factory version of
Arm Trusted Firmware provided by Marvell.

Second patch depends on the first patch, so please add appropriate
Fixes/Cc:stable@ tags to have both patches correctly backported to
stable kernels.

I have tested both patches with Marvell ATF firmware ebin-17.10-uart.zip
and with upstream ATF+uboot and aardvark was initialized successfully.
Without this patch series on ebin-17.10-uart.zip aardvark initialization
