drm/rcar-du: Write DPTSR only if the second source exists

Currently the driver always writes DPTSR when setting up the hardware.
However, writing the register is only meaningful when the second source
for a plane is used, and the register is not even documented for SoCs
that do not have the second source.

So move the write behind a condition.

drm/rcar-du: dsi: Fix PHY lock bit check

The driver checks for bit 16 (using CLOCKSET1_LOCK define) in CLOCKSET1
register when waiting for the PPI clock. However, the right bit to check
is bit 17 (CLOCKSET1_LOCK_PHY define). Not only that, but there's
nothing in the documents for bit 16 for V3U nor V4H.

So, fix the check to use bit 17, and drop the define for bit 16.

drm: remove driver date from struct drm_driver and all drivers

We stopped using the driver initialized date in commit 7fb8af6798e8
("drm: deprecate driver date") and (eventually) started returning "0"
for drm_version ioctl instead.

Finish the job, and remove the unused date member from struct
drm_driver, its initialization from drivers, along with the common
DRIVER_DATE macros.

v2: Also update drivers/accel (kernel test robot)
