[PATCH 1/4] drm: rcar-mipi-dsi: Fix CLOCKSET1_LOCK definition

From: Takeshi Kihara <takeshi.kihara.df at renesas.com>

Version 0.51 of the Renesas R-Car Gen4 TRM reports bit 16 of the
CLOCKSET1 register of the DSI transmitter module to be a reserved
field.

Fix this by correcting the CLOCKSET1_LOCK definition to match the TRM
and remove the CLOCKSET1_LOCK_PHY definition, as the register is simply
called "lock" in the datasheet.
