[PATCH v2 11/11] pci: dwc: pcie-kirin: cleanup kirin970_pcie_get_eyeparam()

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

Cleanup the routine, to let it clearer that eye_param is optional and
that, if not specified, the driver will assume the default.

While here, also drop the useless debug prints.
