defaultenv: Fix dependencies ...

The defaultenv should be rebuilt once a file in it has changed.
the genenv script always generates the environment file to a temporary
file. Only if it has changed to the last target file the temporary file
is moved over the target file. This means we always have to call genenv,
thus replace "if_changed" with "cmd".
With this dependencies are correctly tracked. New or changed files
result in new image builds whereas unchanged environments do not
unnecessarily result in new images.

not longer placed in imx subdir. So the subdir can be removed from the

usb: imx: Do not disable VBUS on ehci_register()'s success ...

Original code was written to exit early on ehci_register()'s
success. As a part of e3eb0c729b, however, it was modified to to early
exit on failure instead. This resulted in VBUS being erroneously
disabled after EHCI controller was added, thus breaking USB on some
i.MX boards (confirmed on ZII's RDU2).

clk: at91: update to PMC bindings ...

Based on kernel 5.0-rc6 update at91 clk support
to match the new PMC bindings.

Manually added all changes done in the kernel from 4.9-rc3 to 5.0-rc6.
New drivers required was added as seperate commits.

This includes dt-compat code required to support at91sam5d3,
as this is not yet ported to use the new PMC bindings.

clk-programmable saw some extra changes - it had never been bulit.
It is used only by at91sama5d2 - and barebox has no board support for
this cpu (yet).

The CONFIG_SOC symbols is used to select the relevant drivers.
CONFIG_SOC_SAM9 selects several drivers, and in the future
this can be split to keep the image size down.

In the kernel CLK_OF_DECLARE_DRIVER() can be used for a two step init.
In barebox this is a simple one step init.
It was added to have less differences between the kernel and the barebox
versions of the drivers.

clk: at91: add dt-compat to PMC bindings ...

As the sama5d3 based microchip-ksz9477-evb board still uses the old
bindings, the dt-compat.c code is ported as well. This can be removed
when all in-kernel at91 boards have been ported to the new bindings.

kbuild: Add missing semicolon ...

Fixes: 4fafb35d925e5 ("kbuild: cherry-pick changes from Linux v5.0-rc3")

The change cherry-picked from the Kernel commit 7d0ea2524202 ("kbuild: use
'else ifeq' for checksrc to improve readability") also removed the
trailing semicolons from the cmd_*checksrc lines. These were removed in
kernel commit e5d289100d ("kbuild: remove trailing semicolon from cmd_*
passed to if_changed_rule"), but seems the barebox Kbuild version is not
yet ready for this change. Without the semicolons a make C=1 build fails
with:
