Commit 026d70dcfe5d ("clk: microchip: core: allow driver to be compiled
with COMPILE_TEST") introduces a typo when referring to a config option in
an ifdef directive.
Fix this typo.

This driver currently only supports builds against a PIC32 target. To
avoid future breakage in the future, let's update the Kconfig and the
driver so that it can be built with CONFIG_COMPILE_TEST enabled.
Note that with the existing asm calls is not how I'd want to do this
today if this was a new driver, however I don't have access to this
hardware. To avoid any breakage, let's keep the existing behavior.

Use the linux/platform_data/pic32.h include instead of
asm/mach-pic32/pic32.h so that the asm variant can be dropped. This
is in preparation for allowing some drivers to be compiled on other
architectures with COMPILE_TEST enabled.

roclk_get_parent() and sclk_get_parent() has the possibility of
returning -EINVAL, however the framework expects this call to always
succeed since the return value is unsigned.
If there is no parent map defined, then the current value programmed in
the hardware is used. Let's use that same value in the case where
-EINVAL is currently returned.
This index is only used by clk_core_get_parent_by_index(), and it
validates that it doesn't overflow the number of available parents.

pic32_sclk_ops previously had a sclk_round_rate() member, and this was
recently converted over to sclk_determine_rate() with the help of a
Coccinelle semantic patch. pic32_sclk_ops now has two conflicting
determine_rate ops members.
Prior to the conversion, pic32_sclk_ops already had a determine_rate
member that points to __clk_mux_determine_rate(). When both the
round_rate() and determine_rate() ops are defined, the clk core only
uses the determine_rate() op. Let's go ahead and drop the recently
converted sclk_determine_rate() to match the previous functionality
prior to the conversion.

Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

I also reordered a couple includes when they weren't alphabetical and
removed clk.h from kona, replacing it with clk-provider.h because
that driver doesn't use clk consumer APIs.
