[PATCH] lib: utils/fdt: update fdt_parse_aplic_node()

[Huang Borong]

1. Initialize struct imsic_data imsic to 0 at definition to prevent the
   use of uninitialized memory, ensuring the variable starts with known
   values.

2. Remove the redundant memset call on the "aplic" parameter since the
   memory for aplic is allocated using sbi_zalloc() by the caller
   irqchip_aplic_cold_init(), which guarantees it is already set to 0.
