[PATCH 2/4] lib: utils: irqchip: aplic: Add aplic_get_list() accessor

["David E. Garcia Porras" <david.garcia@aheadcomputing.com>]

The internal aplic_list is static, preventing platform code from
iterating over registered APLIC devices for custom configuration
(e.g. enabling domain-level interrupts in MSI delivery mode).

Add aplic_get_list() to return a pointer to the list head, allowing
platform code to walk registered APLIC devices without breaking
encapsulation by extern-ing the static list directly.
