This patch adds can_clk function to r8a7743/r8a7791 which is cleaner,
and allows for independent configuration.
We keep the can_clk* pins definitions from within can0_groups and
can1_groups for uniformity and backwards compatibility.

Till now, DE2 driver supported only UI planes. Before we add support for
VI planes, lets split out UI layer specific code from common parts. This
commit does the following:
- renames sun8i_layer.c to sun8i_ui_layer.c
- moves UI channel specific code to sun8i_ui_layer.c
- moves common code from sun8i_layer.c to sun8i_mixer.c
- renames function and structure names so it is apparent where they
belong to
No functional change is made.

Till now, plane selection was hardcoded to first overlay in first UI
channel and layer parameter is unused.
Rename and add parameters to layer functions so they would represent HW
more accurately and start using then.
It turns out that overlays don't fit well in current DRM design, because
they can't be blended together or scaled independetly when they are set
to same channel. Because of that, always use only first overlay in each
channel.

Current code sets alpha mode to global alpha mode and global alpha
value to 0xff which is totaly opaque. That is not needed for two
reasons:
- only one plane is active and thus it can be blended only with
background, which is black,
- it will hinder proper blending when more than one plane is supported
Default mode (0) considers pixel alpha value or 0xff if pixel has
no alpha information. Global alpha value is ignored in this case.
Because of that, just remove the code.

Include the OF-based modalias in the uevent sent when registering devices
on the sunxi RSB bus, so that user space has a chance to autoload the
kernel module for the device.
Fixes a regression caused by commit 3f241bfa60 ("arm64: allwinner: a64:
pine64: Use dcdc1 regulator for mmc0"). When the axp20x-rsb module for
the AXP803 PMIC is built as a module, it is not loaded and the system
ends up with an disfunctional MMC controller.

Prevent that a prefix flag is set based on invalid configuration data.
The validity.verify_base flag should only be set for alias devices.
Usually the unit address type is either one of base, PAV alias or
HyperPAV alias. But in cases where the unit address type is not set or
any other value the validity.verify_base flag might be set as well.
This would lead to follow on errors.
Explicitly check for alias devices and set the validity flag only for
them.

getnstimeofday() and timespec are deprecated since they can
overflow on 32-bit architectures. This simply changes to the
explicitly typed timespec64 version that doesn't have that
problem.
It would be nice to also convert to monotonic timestamps
and call ktime_get_ts64() rather than ktime_get_real_ts64(),
but that would be a user-visible change.
