phy: qualcomm: phy-qcom-eusb2-repeater: Use regmap_fields

[ Upstream commit 4ba2e527 ]

Switch to regmap_fields, so that the values written into registers are
sanitized by their explicit sizes and the different registers are
structured in an iterable object to make external changes to the init
sequence simpler.
