Andriy Gelman 727e589448 drivers: interrupt_controller: Add XMC4XXX ERU driver 
In Infineon XMC4XXX SoCs, gpio interrupts are triggered via an
Event Request Unit (ERU) module. A subset of the gpios are
connected to the ERU. The ERU monitors edge triggers and creates
a SR.

This driver configures the ERU for a target port/pin combination
for rising/falling edge events. Note that the ERU module does
not generate SR based on the gpio level. Internally the ERU
tracks the *status* of an event. The status is set on a positive
edge and unset on a negative edge (or vice-versa depending on
the configuration). The value of the status is used to implement
a level triggered interrupt; The ISR checks the status flag and
calls the callback function if the status is set.

The ERU configurations for supported port/pin combinations are
stored in a devicetree file dts/arm/infineon/xmc4xxx_x_x-intc.dtsi.
The configurations are stored in the opaque array
uint16 port_line_mapping[].
