This series fixes and extends the Rockchip Innosilicon CSI D-PHY driver
to support data rates up to 2500 Mbps and adds optional board-specific
clock lane phase tuning for signal integrity.

Patch 1 fixes an off-by-one error in the rk1808 hsfreq range table:
the final entry was capped at 2499 Mbps, causing a rejection of the
maximum supported rate of 2500 Mbps.

Patches 2 and 3 add an optional rockchip,clk-lane-phase device tree
property that allows tuning the clock lane sampling phase in ~40 ps
steps to compensate for board-level signal integrity variations.
