lib: utils/irqchip: Add shared MMIO region for PLIC in root domain
On platforms with Smepmp, the MMIO regions accessed by M-mode need to be explicitly marked with M-mode only read/write or shared (both (M-mode and S-mode) read/write permission. If the above is not done then runtime PLIC access from M-mode on platforms with Smepmp will result in access fault when further results in CPU hotplug not working.
