The EMC clock needs to carefully coordinate with the EMC controller
programming to make sure external memory can be properly clocked. Do so
by hooking up the EMC clock with an EMC provider that will specify which
rates are supported by the EMC and provide a callback to use for setting
the clock rate at the EMC.

A proper External Memory Controller clock rounding and parent selection
functionality is required by the EMC drivers, it is not available using
the generic clock implementation because only the Memory Controller driver
is aware of what clock rates are actually available for a particular
device. EMC drivers will have to register a Tegra-specific CLK-API
callback which will perform rounding of a requested rate. EMC clock users
won't be able to request EMC clock by getting -EPROBE_DEFER until EMC
driver is probed and the callback is set up.
The functionality is somewhat similar to the clk-emc.c which serves
Tegra124+ SoCs. The later HW generations support more parent clock sources
and the HW configuration / integration with the EMC drivers differs a tad
from the older gens, hence it's not really worth to try to squash
everything into a single source file.

Standby status is provided for certain clkctrl clocks to see if the
given module has entered standby or not. This is mostly needed by
remoteproc code to see if the remoteproc has entered standby and the clock
can be turned off safely.

Add common library code for the Analog Bits Wide-Range PLL (WRPLL) IP
block, as implemented in TSMC CLN28HPC.
There is no bus interface or register target associated with this PLL.
This library is intended to be used by drivers for IP blocks that
expose registers connected to the PLL configuration and status
signals.
