dev_dbg is a no-op when debugging is disabled, so no need for extra ifdefs.

4ed5b77 ("i.MX: i2c: Add Vybrid support") introduced regshifts for the
register offsets, but missed to adjust the register offset for the
FSL_I2C_DFSRR register (which exists only on PowerPC). Fix this.

i2c_fsl_write() and i2c_fsl_read() take exactly one i2c message, not
multiple ones, hence rename the variable from "msgs" to "msg".

We have to write to FSL_I2C_I2DR and wait for completion/ack three
times in the code. Instead of open coding it each time create a
helper function for it.

We can track the stopped status in the I2CR_MSTA bit, no need for an
extra variable. Also we can call i2c_fsl_stop() instead of open coding
it in i2c_fsl_read().

In i2c_fsl_stop() we call i2c_fsl_bus_busy() a second time when it
fails. If it fails once it won't succeed the second time, so drop
the second call.

The BREN bit tells us a watermark level sized buffer is ready for read.
Instead of testing it before each FIFO read we must only check it once
and then read a watermark level sized buffer. This is at least necessary
on Layerscape, otherwise timeouts occur while reading the buffer.

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.

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.

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).
Fixes: e3eb0c729b ("usb: host: ehci: add ehci_unregister()")
