    arm64/gicv3: correct the size of the distributor resource
    
    Use the GICD_SIZE macro (0x10000), which is half the size of the current
    fixed-sized mapping (128 * 1024 == 0x20000).
    
    In ARM64 Hyper-V instances, it seems the Distributor's registers are
    located immediately preceding a range of physical memory in the bus
    address space. Thus, when ram0 is attaching and attempts to reserve
    SYS_RES_MEMORY resources corresponding to its physmem ranges, it fails,
    because the first 0x10000 bytes of this range are already owned by gic0.
