SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2

changes for SH7786, including wiring up the IPIs properly, enabling
IRQ_PER_CPU, and so forth.

This tidies up the boot_cpu_data.flags probing on SH-4A. All of them have
a few things in common, which we can blindly set, rather than having each
subtype have to set the same flags. We can also make assumptions about
cache ways and the validity of PTEA, so this also kills off CPU_HAS_PTEA
as a config option. There was also a bug in the FPU probing, which is now
tidied up.

This adds a new SH_CLK_CPG for parts that have CPG support.
SH_CLK_CPG_LEGACY is made to depend on this, and still needs to be set
for platforms that want clock-cpg to register the legacy clocks. With
this new config item in place, it is now possible to start layering more
generic CPG code in place while other platforms transition off of the
legacy clocks.

This updates the SH7785 CPU code as well as the SH7785LCR board support

Now that everything has converted over to generic timekeeping, we need an

maintain the same behaviour.
