sata_mv: cosmetic renames
Add _OFS suffix to more of the register offset names,
for consistency with the rest of the driver.
Also tag the defines for LTMODE and PHY_MODE4 to note
that read-after-write is necessary when updating those regs.
No code changes here.
[NOTE: this commit is undone a few commits later]
