phy: qualcomm: eusb2-repeater: Rework init to drop redundant zero-out loop

[ Upstream commit 734550d6 ]

Instead of incrementing the base of the global reg fields, which renders
the second instance of the repeater broken due to wrong offsets, use
regmap with base and offset. As for zeroing out the rest of the tuning
regs, avoid looping though the table and just use the table as is,
as it is already zero initialized.
