xen: arm: correctly round down MFN to 1GB boundary make sure pagetable mask macros as physaddr size

~FIRST_MASK is nothing like correct for rounding down an MFN. It is the
inverse *and* an address not a framenumber so wrong in every dimension! We
cannot use FIRST_MASK since that would mask off any zeroeth level bits.
Instead calculate the correct value from FIRST_SIZE.
