Previously aardvark PCI controller set speed to gen2. Now it reads speed
from Device Tree and as default use maximal possible speed which is gen3.

Because Espressobin has advertised only PCI Express 2.0 capability and
previous value was gen2, define max-link-speed to 2, so there would not be
any configuration change.

When chaning dts files in arch/arm64/boot/dts/marvell, use subject
prefix
  arm64: dts: marvell:
for espressobin for example
  arm64: dts: marvell: espressobin:

instead of
  dts: espressobin
or
  dts: aardvark
