[Skiboot] [PATCH] phb4: Fix TVE encoding for start address

[Frederic Barrat]

>From the phb4 spec, when encoding the TVE, the pci start address bits
49:24 are encoded in bits TVE[52:53]||[0:23].
The mask to select bits 47:24 is incorrectly set. It should be
0xffffff000000, shifted left by 16, i.e. 0xffffff << 40
