If an error occurs after a successful 'cdns_pcie_init_phy()' call, it must
be undone by a 'cdns_pcie_disable_phy()' call, as already done above and
below.

Update the 'goto' to branch at the correct place of the error handling
path.

Hi Christophe,

Thank you for sending the patch over!

Just a tiny nit-pick: there is no need to surround function names in single
quotes in the subject and in the commit message.

Here, in the above sentence, you could simply mention that this is needed
for the device to be correctly powered down should there be an error, and
reference to the "above" and "below" code.
