Remove od parameters from pll clocks and add post dividers clocks
instead. Some clock, especially the one which feature several ods,
may provide output between those ods. Also, some drivers, such
as the hdmi driver, may require a more detailed control of the
clock dividers, compared to what CCF would perform automatically.
One added benefit of removing ods is that it also greatly reduce the
size of the rate parameter tables.
In the future, we could possibly take the predivider 'n' out of this
driver as well. To do so, we will need to understand the constraints
for the PLL to lock and whether or not it depends on the input clock
rate.

GEN_CLK is able to route several internal clocks to one of the SoC
pads. In the future, even more clocks could be made accessible using
cts_msr_clk - the clock measure block.

Adding clocks for the pcie driver. Due to the ASIC design,
the pcie controller re-use part of the mipi clock logic,
so the mipi clock is also added.

Fdiv fixed dividers clocks of the fixed_pll can actually gate
independently. We never had an issue so far because these clocks
were provided 'enabled' by the bootloader.
Add these gates to enable/disable the clocks when required.

mpll clocks parent can actually be divided by 1 or 2. So far, this
divider has always been set to 1, so the calculation was correct.
Now that we know it exists, model the tree correctly. If we ever get
a platform where the divider is different, we won't get into trouble

Add the hifi pll to the axg clock controller. This clock maybe used as an
input of the axg audio clock controller. It uses the same settings table
as the gp0 pll but has a frac parameter allowing more precision.

The mpll clock is a kind of fractional divider which can gate.
When the RW operation have been added, enable/disable ops have been
mistakenly inserted in this driver. These ops are essentially a
poor copy/paste of the generic gate ops.
This change removes the gate ops from the mpll driver and inserts a
generic gate clock on each mpll divider, simplifying the mpll
driver and reducing code duplication.
