The NAND controller within EBI2 requires EBI2_CLK and
EBI2_ALWAYS_ON_CLK clocks. Create structs for these clocks so
that they can be used by the NAND controller driver. Add an entry
for EBI2_AON_CLK in the gcc-ipq806x DT binding document.

In the current parent mapping code, we can get duplicate or inconsistent
indexes, which leads to discrepancy between the number of elements in the
array and the number of parents. Until now, this was solved with some
reordering but this is not always possible.
This patch introduces index tables that are used to define the relations
between the PLL source and the hardware mux configuration value.
To accomplish this, here we do the following:
- Define a parent_map struct to map the relations between PLL source index
and register configuration value.
- Add a qcom_find_src_index() function for finding the index of a clock
matching the specific PLL configuration.
- Update the {set,get}_parent RCG functions use the newly introduced
parent_map struct.
- Convert all existing drivers to the new parent_map tables.

The pre-divider for the sdc clocks only has 2 bits in it, so we
can't possibly divide by anything larger than 4 here.
Furthermore, we program the value of ~(n - m) and the n value is
larger than 8 bits (max of 256). Replace this entry with 200kHz
which is close enough to 144kHz to be usable.

Add a driver for the global clock controller found on IPQ8064 based
platforms. This should allow most non-multimedia device drivers to probe
and control their clocks.
This is currently missing clocks for USB HSIC and networking devices.
