irqchip/riscv-intc: Fix SMP=n boot with ACPI
When CONFIG_SMP is disabled, the static array rintc_acpi_data with size
NR_CPUS is not sufficient to hold all RINTC structures passed from the
firmware.
All RINTC structures are required to configure IMSIC/APLIC/PLIC properly
irrespective of SMP in the OS. So, allocate dynamic memory based on the
number of RINTC structures in MADT to fix this issue.
