gpio: lpc32xx: remove unused platform data file

ARM LPC32xx platform is device-tree only, there is no need to keep

definitions should be moved to the driver code, which is the only user
of the removed header file.

gpio: lpc32xx: disable broken to_irq support

gpio: lpc32xx: disable broken to_irq support

The "to_irq" functionality is broken inside this driver since commit
76ba59f8366f ("genirq: Add irq_domain-aware core IRQ handler").

The addition of the new lpc32xx irqchip driver in 4.7, fixed the
lpc32xx platform interrupt issue.

When switching to the new lpc32xx irqchip driver, a warning appear
in the lpc32xx gpio driver: warning: "NR_IRQS" redefined.

To remove this warning (temporary solution), this patch
disables the broken "to_irq" mapping functionality support.

As we want gpio_chip .get() calls to be able to return negative

We do this by using the ret = !!(val) design pattern.

to assign these values with true/false instead of 0/1. The
users outside these subsystems will survive since true/false

- Some conversion to use managed resources devm_* code.
- Some instances of clk_prepare() or clk_prepare_enable() added to
support the new, stricter common clock framework.
- Some for_each_set_bit() simplifications.

Please note that this only reads back the currently programmed output state,
not the actual electrical level in terms of a GPI function. Finally, GPO3 is
