clk: imx6q: handle ENET PLL bypass
The ENET PLL is different from the other i.MX6 PLLs, as it has
multiple outputs with different post-dividers, which are all
bypassed if the single bypass bit is activated. The hardware setup
looks something like this:
_
refclk-o---PLL---o----DIV1-----| \
| | |M |----OUT1
o-----------------------|_/
| | _
| o----DIV2-----| \
| | |M |----OUT2
o-----------------------|_/
| | _
| `----DIV3-----| \
| |M |----OUT3
`-----------------------|_/
The bypass bit not only bypasses the PLL, but also the attached
post-dividers. This would be reasonbly straight forward to model
with a single output, or with different bypass bits for each output,
but sadly the HW guys decided that it would be good to actuate all
3 muxes with a single bit.
So the need to have the PLL bypassed for one of the outputs always
affects 2 other (in our model) independent branches of the clock
tree.
This means the decision to bypass this PLL is a system wide design
choice and should not be changed on-the-fly, so we can treat any
bapass configuration as static. As such we can just register the
post-dividiers with a ratio that reflects the bypass status, which
allows us to bypass the PLL without breaking our abstraction model
and with it DT stability.

clk: renesas: rcar-gen3: Set state when registering SD clocks
The driver tries to figure out which state a SD clock is in when the
clock is registered, instead of setting a known state. This can be
problematic for two reasons.
1. If the clock driver can't figure out the state of the clock,
registration of the clock fails, and setting of a known state by a
clock user is not possible.
2. The state of the clock depends on if and how the bootloader
configured it. The driver only checks that the rate is known, not if
the clock is stopped or not for example.
Fix this by setting a known state and making sure the clock is stopped.

have the requested divider value. Similarly, when the clk is disabled we'll
write a 0 there, but when the clk is enabled we'll restore whatever rate

It does mean that recalc rate will be sort of odd, because when the clk is

So to make things work, we'll need to return the cached rate in recalc rate
when the clk is off and read the hardware when the clk is on.
NOTE for the default off divider, the recalc rate will still return 0 as
there's still no proper preset rate. Enable such divider will give user
