riscv: andes_plic: Fix riscv_get_ipi() mask
Current logic in riscv_get_ipi() for Andes PLICSW does not look
correct. The mask to test IPI pending bits for a hart should be
left shifted by (8 * gd->arch.boot_hart), just the same as what
is done in riscv_send_ipi().
Fixes: 8b3e97badf
("riscv: add functions for reading the IPI status")
