platform: openpiton: fix uninitialized plic_data struct

The plic_data struct was uninitialized. This led to misfunction behavior
since it was subsequently assigned to the global plic struct, and some
struct fields, such as flags and irqchip, contained random values.
The fix proposes to initialize the plic_data to the global plic struct,
so, after parsing the fdt, the fields of the struct will be set to the
default values set in global plic struct definition, or the parsed values
in the fdt, or zero.
