    xen/arm: fix mask calculation in pdx_init_mask
    
    The mask calculation in pdx_init_mask is wrong when the first bank
    starts at address 0x0. The reason is that pdx_init_mask will do '0 - 1'
    causing an underflow. As a result, the mask becomes 0xffffffffffffffff
    which is the biggest possible mask and ends up causing a significant
    memory waste in the frametable size computation.
    
    For instance, on platforms that have a low memory bank starting at 0x0
    and a high memory bank, the frametable will end up covering all the
    holes in between.
    
    The purpose of the mask is to be passed as a parameter to
    pfn_pdx_hole_setup, which based on the mask parameter calculates
    pfn_pdx_hole_shift, pfn_pdx_bottom_mask, etc. which are actually the
    important masks for frametable initialization later on.
    
    pfn_pdx_hole_setup never compresses addresses below MAX_ORDER bits (1GB
    on ARM). Thus, it is safe to initialize mask passing 1ULL << (MAX_ORDER
    + PAGE_SHIFT) as start address to pdx_init_mask.

    xen: Replace u64 with uint64_t in pdx_init_mask() and callers
    
    Xen is phasing out the use of u64 in favor of uint64_t. Therefore, the
    instance of u64 in the pdx_init_mask() (and the callers) are now
    replaced with uint64_t. Take the opportunity to also modify
    srat_region_mask as this is used to store the result of pdx_init_mask().
