[PATCH 1/2] nubus.h: add ULL suffix to NUBUS_SUPER_SLOT_SIZE and NUBUS_SUPER_SLOT_SIZE

[Mark Cave-Ayland]

Coverity thinks that the slot_offset multiplications in nubus_device_realize()
might overflow because the resulting hwaddr is 64-bit whilst the multiplication
is only done at 32-bits.

Add an explicit ULL suffix to NUBUS_SUPER_SLOT_SIZE and NUBUS_SUPER_SLOT_SIZE
to ensure that the multiplication is also done at 64-bits.
