drivers/core/gic.c: Set priority mask to allow NS interrupts

The non-secure world's view of interrupt priorities only allows
it to set priorities between 0x80 and 0xff. This means that the
secure world has to set the GICC_PMR (priority mask register) to
a value that allows NS interrupts, otherwise the non-secure
world will never see interrupts and has no way to set the
priorities so that it will ever see them.

Fix a comment typo while we're here.
