irqchip/renesas-intc-irqpin: Improve clock error handling and reporting
If the Renesas External IRQ Pin driver cannot find a functional clock,
it prints a warning, .e.g.
renesas_intc_irqpin fe78001c.interrupt-controller: unable to get clock
and continues, as the clock is optional, depending on the SoC type.
This warning may confuse users.
To fix this, add a flag to indicate that the clock is mandatory or
optional, and add a few more compatible entries:
- If the clock is mandatory (on R-Mobile A1 or SH-Mobile AG5), a
missing clock is now treated as a fatal error,
- If the clock is optional (on R-Car Gen1, or using the generic
"renesas,intc-irqpin" compatible value), the warning is no longer
printed.
This requires making struct intc_irqpin_irlm_config more generic by
renaming it to intc_irqpin_config, and adding a flag to indicate if IRLM
is needed.
The new clock flag is merged with the existing shared_irqs boolean into
a bitfield to save space.
