Subject: [PATCH v2 5/8] phy: phy-snps-eusb2: make repeater optional

Some platforms initialize their eUSB2 to USB repeater in the previous
stage bootloader and leave it in a working state for linux. Make the
repeater optional in order to allow for reusing that state until
proper repeater drivers are introduced.
